LBUA5QJ2AB-828 - UWB + BLE 5.2 Combo Module | Murata
The Murata LBUA5QJ2AB-828 is a hostless UWB (ultra-wideband) + Bluetooth 5.2 Low Energy combo transceiver module supporting UWB operation across the 6250 MHz to 8250 MHz range (IEEE 802.15.4z channels, Band 5 and Band 9) in a compact 10.5 x 8.3 mm surface-mount LGA package with 97 pins. Antenna is not included, allowing design flexibility with external UWB and BLE antennas. An ultra-wideband module is a short-range, high-precision radio module that transmits nanosecond-scale pulses across very wide bandwidths, enabling centimeter-level distance measurement (secure ranging) that narrowband radios such as Bluetooth or Wi-Fi cannot achieve. UWB modules sit within the broader RF transceiver module hierarchy, and combo modules like this one pair UWB ranging with a conventional low-power radio for wake-up, control, and data functions. Key features include the Qorvo QM33120W UWB chipset paired with an integrated Nordic Semiconductor nRF52840 that provides Bluetooth 5.2 LE, firmware update, and wake-up control. The module is FCC/IC/TELEC reference certified, dramatically reducing end-product regulatory effort. An integrated 3-axis accelerometer supports battery-saving duty cycling, and reference clocks for both the UWB chip and MCU are embedded on the module, simplifying BOM and calibration. Architecturally, the hostless design means the nRF52840 manages the UWB radio autonomously, allowing UWB ranging sessions to execute without waking the host processor. The nRF52840 provides 1 MB flash and 256 kB RAM for embedded application code, with host interfaces including I2C, SPI, UART, and USB. Typical applications include secure car-access key fobs and automotive door-zone detection, indoor asset tracking and real-time location systems (RTLS), and smart-door locks and access-control systems where UWB secure ranging prevents relay attacks. Design consideration: since the antenna is not integrated, place the module near the antenna connectors with controlled-impedance RF traces and follow Murata's reference layout for the 6.5 GHz and 8 GHz bands to pass certification.

LBWA0ZZ2HK - Sub-1GHz Wi-Fi HaLow 11ah Module | Murata | IoT
The Murata LBWA0ZZ2HK (Type 2HK) is a long-range Sub-1GHz Wi-Fi HaLow system-on-module based on the NEWRACOM NRC7394 chipset, supporting IEEE 802.11ah SISO operation in the 902 MHz to 928 MHz band with a communication range of up to 2 km, packaged as a compact surface-mount connectivity module. A Wi-Fi HaLow module is a wireless connectivity subsystem that implements the IEEE 802.11ah standard, which operates in sub-1 GHz license-exempt spectrum rather than the crowded 2.4 GHz and 5 GHz bands used by conventional Wi-Fi. Within the network hierarchy, it sits between a host microcontroller or application processor and the RF front end and antenna, offloading the full MAC and PHY of the 802.11ah S1G standard. Sub-1 GHz radios trade raw throughput for dramatically longer range, better penetration through walls and foliage, and lower power consumption, making HaLow the Wi-Fi-family choice for IoT mesh and star networks where 2.4 GHz Wi-Fi, BLE, or 802.15.4 range is insufficient. Key features of the LBWA0ZZ2HK include its NRC7394 chipset base supporting 802.11ah SISO, coverage of the 902-928 MHz US band, ultra-low power consumption with advanced sleep features for battery operation, an embedded RTOS with IP-native application support, and Murata-grade module integration that simplifies regulatory certification (FCC ID VPYLBWA0ZZ2HK). Technically, the module integrates the NRC7394 SoC, crystal, RF matching network, and flash into a single shielded land-grid package. The 2 km link range is achieved by combining narrowband sub-1 GHz propagation with the robust modulation and coding schemes of 802.11ah. The embedded RTOS and TCP/IP stack allow the host processor to use simple AT-style or socket interfaces instead of implementing a Wi-Fi stack. Typical applications include smart utility metering, industrial sensor networks, smart-city infrastructure, agricultural monitoring, and battery-powered security and access-control devices - all scenarios where devices are spread over campus-scale distances and must run for years on batteries. Design-wise, provide a clean 3.3 V supply with local decoupling, route the antenna per Murata's FCC integration instructions, and account for HaLow transmit bursts in battery budget calculations rather than using average current alone.

LBWA0ZZ2HL - Sub-1GHz Wi-Fi HaLow 802.11ah Module | Murata
The Murata LBWA0ZZ2HL (Type 2HL) is a long-range Sub-1GHz Wi-Fi HaLow system-on-module based on the NEWRACOM NRC7394 chipset, supporting IEEE 802.11ah SISO operation from 750 MHz to 950 MHz with data rates up to 15 Mbps, output power up to 17 dBm, and line-of-sight communication range up to 1 km from a 2.7 V to 3.6 V supply. A Wi-Fi HaLow module is a wireless connectivity module that implements the IEEE 802.11ah Sub-1 GHz (S1G) amendment of the Wi-Fi standard. Unlike conventional 2.4 GHz and 5 GHz Wi-Fi, HaLow trades peak bandwidth for substantially greater range, better wall-penetration, and lower power consumption, making it a member of the low-power wide-area (LPWAN) connectivity family alongside LoRa and NB-IoT, while retaining native IP networking and Wi-Fi security. Key features of the LBWA0ZZ2HL include operation across key regional Sub-1 GHz bands (the HL variant covers 750-950 MHz bands for regions such as Europe, Japan and others, while the companion HK variant targets 902-928 MHz), ultra-low power consumption for battery-powered IoT endpoints, and data rates up to 15 Mbps - far higher than typical LPWAN technologies. The integrated NRC7394 SoC handles MAC, baseband and RF in a single chipset, simplifying host integration over SDIO/SPI interfaces. Technically, the module implements 802.11ah SISO with standard Wi-Fi security, allowing direct IP connectivity to HaLow access points. Murata, as a leading module manufacturer, provides certification-ready design that reduces end-product regulatory burden across key regions. According to Murata product literature, the Type 2HL is designed specifically for the connectivity needs of Internet of Things (IoT) devices. Typical applications include smart utility metering, industrial sensors, building automation, smart city infrastructure, and agricultural monitoring - all scenarios requiring multi-hundred-meter to kilometer-scale links with years of battery life. Designers should verify regional RF regulatory certification (the HL and HK variants cover different frequency bands) and confirm antenna matching and supply filtering per the manufacturer datasheet. This page synthesizes verified distributor and manufacturer data, drop-in alternatives, and practical design notes not found in the manufacturer datasheet.
LE910C1-EU - LTE Cat.1 10/5 Mbps Module | Telit Cinterion
The Telit Cinterion LE910C1-EU is an LTE Cat.1 cellular IoT transceiver module delivering 10 Mbps downlink and 5 Mbps uplink data rates, compliant with 3GPP Release 10, housed in a compact LGA (land grid array) surface-mount form factor with an optional quad-constellation GNSS receiver supporting GPS, GLONASS, Galileo, BeiDou, and QZSS. An LTE Cat.1 module is a category of cellular RF transceiver module that provides full-duplex LTE connectivity at modest data rates, sitting within the broader hierarchy of cellular modems: M2M module -> LTE transceiver module -> wireless communication IC. Cat.1 is widely adopted as the migration path from 2G/3G for machine-to-machine devices because it uses the existing LTE network infrastructure without the complexity of Cat-M1 or NB-IoT, while still supporting voice and data. Key features of the LE910C1-EU include the 10/5 Mbps throughput profile, 3GPP Rel 10 compliance with Rel 12-ready MTC platform features, integrated TCP/IP and UDP/IP protocol stacks, and peripheral connectivity via USB 2.0 HS, UART, and user-definable GPIOs. These characteristics make it well suited to devices that need dependable, always-on wide-area connectivity without a host-side network stack. The module is part of Telit's flagship xE910 family, whose design-once, use-anywhere philosophy allows LE910C1 variants to serve as pin-to-pin compatible replacements within the same LGA footprint for devices based on earlier 2G, 3G, and LTE family members. The ThreadX RTOS-based firmware platform simplifies application integration, and the LE910Cx family is also offered in Linux-based SKUs for more demanding gateway applications. Typical applications include smart metering, asset tracking and fleet telematics, industrial gateways and routers, security and alarm panels, and connected point-of-sale terminals, where European-band LTE coverage and low-power, long-lifecycle operation are priorities. When designing with the LE910C1-EU, budget for a proper RF layout: the antenna is not included, so PCB antenna feed matching, keep-out zones, and supply decoupling follow the Telit LE910C1 Series hardware user's manual guidance for the LGA footprint. This page synthesizes distributor pricing and availability, drop-in alternatives within the xE910 family, and practical design guidance not consolidated in the manufacturer datasheet.
LM048 - Class 1 Bluetooth RS232 Serial Adapter 100m | LM Technologies
The LM Technologies LM048 is a Class 1 Bluetooth® Serial Adapter (RS232) that provides a secure and reliable wireless link replacing legacy RS232 cables between DTE master devices and DCE peripherals such as printers, data loggers, and digital signalling equipment. Housed in a compact plastic enclosure and billed by the manufacturer as the world's smallest Bluetooth® serial adapter, the LM048 delivers up to 100 m line-of-sight range using an onboard antenna while operating from either RS232 Pin 9 (4 V to 13 V) or a Mini-USB supply. A Bluetooth® serial adapter is a self-contained cable-replacement module that bridges a wired RS232 UART interface to a Bluetooth SPP/Serial Port Profile link. Inside the adapter, a Bluetooth baseband IC handles the v2.0/v2.1 + EDR radio (Class 1, up to +18 dBm Tx) and the SPP stack; an RS232 transceiver converts UART logic levels to the ±5 V to ±15 V signaling required by RS232 peripherals. Pairing is transparent to the host: RS232 control lines DTR, DSR, RTS, and CTS are replicated end-to-end over the wireless link via the LM048's patented firmware, allowing legacy Windows/Linux serial applications to operate without modification. The headline specifications include Bluetooth® v2.0/v2.1 with EDR (3 Mbps nominal), Class 1 output power (approximately +18 dBm Tx), -86 dBm Rx sensitivity, and adaptive frequency hopping across the 2.402 GHz to 2.480 GHz ISM band. The adapter accepts RS232-standard baud rates (typical coverage 1.2 kbps up to 460 kbps per public listings) and operates from -20 °C to +75 °C. Power can be sourced from RS232 Pin 9 (4 V to 13 V) or from a Mini-USB port, and the plastic housing exposes a slide switch plus LEDs for status and pairing feedback. A pair of LM048 adapters using their unique hardware and firmware combination can act as a transparent serial cable replacement, removing the need for driver changes on the host. The unit carries relevant Bluetooth SIG certifications and CE/FCC compliance marks as listed in the manufacturer datasheet. Typical applications include industrial RS232 cable replacement, factory-floor data loggers, point-of-sale printers, bar-code scanners, and remote telemetry units. Designers typically route 5 V to 9 V to Pin 9 and connect TX/RX directly to the host UART bridge. When designing a drop-in cable-replacement node, choose between powering from the RS232 Pin 9 line or USB Mini; a pair of LM048 units gives a true transparent null-modem replacement. Note that throughput tops out near the 460 kbps baud ceiling and the radio is limited to Bluetooth v2.0/v2.1 + EDR, not BLE 5.x. This page synthesizes distributor pricing for the LM048, same-brand LM Technologies variants (LM048 v2, LM058, LM400, LM072) and practical drop-in guidance not collected in the manufacturer datasheet.
LM068 - Bluetooth 5.0 Dual Mode RS232 Serial Adapter | LM Technologies
The LM Technologies LM068 is a Bluetooth 5.0 Dual Mode RS232 Serial Adapter packaged as a standalone module with an embedded Bluetooth 5.0 stack. It operates with a supply voltage of 4V to 12V, supports data rates up to 3 Mbps, and is designed to replace wired RS232 cables between a master (DTE) device and slave (DCE) devices such as printers, data loggers, and digital signalling instruments. The adapter runs on an internal microcontroller paired with an 8 Mbit flash memory for application storage, enabling firmware configurability through the LM149v2 host utility. A Bluetooth serial adapter is a self-contained wireless bridge that replaces a legacy UART/RS232 cable with a Bluetooth link. In the broader taxonomy it sits under wireless modules -> RF modules -> RF transceivers -> communication ICs -> semiconductors. The adapter exposes a standard DB9 RS232 connector on the DTE side and converts the UART traffic to a Bluetooth 5.0 link on the slave side. Dual Mode means it can connect to both Bluetooth Classic (BR/EDR) and Bluetooth Low Energy (BLE) hosts, providing flexibility for legacy SPP-style serial replacement as well as modern low-power BLE devices. Key features of the LM068 include Bluetooth 5.0 dual mode support (Classic + BLE), a configurable firmware via the LM149v2 utility, configurable baud rate, data bits, parity and flow control, support for SPP (Serial Port Profile) over Classic, and a small physical footprint of 46.3 mm x 34 mm x 16 mm. The power input is versatile: USB-Mini, DB9, or an external AC adaptor. Settings persist across power cycles, eliminating the need to reconfigure on every boot. The adapter also supports auto-connect and discoverable/non-discoverable modes, simplifying integration in industrial machines where operators frequently reconnect cables between cycles. The internal architecture pairs a microcontroller with a Bluetooth 5.0 module, with the MCU handling profile bridging and configuration. Because the stack is embedded, the host CPU never sees raw radio activity; it only exchanges UART bytes, simplifying software integration on systems that cannot host a Bluetooth stack (older PLCs, microcontrollers without BLE, lab instruments). Typical applications include replacing RS232 cables in industrial machinery, wireless connection to data loggers and printers, point-to-point serial tunneling for embedded devices, and office equipment that needs occasional wireless configuration access without permanent cabling. The wide 4-12V input range lets it draw power from the host's existing DC rail or an AC wall adaptor. When selecting the LM068, ensure that the target host device has an RS232 DB9 port, or plan for a USB-to-RS232 converter. The adapter cannot exceed approximately 3 Mbps aggregate throughput, which is faster than classic RS232 (115.2 kbps typical) but considerably slower than modern Wi-Fi or Ethernet alternatives. Pick this part when you need a deterministic cable replacement with minimal configuration, not for high-bandwidth streaming. This page synthesizes distributor availability, configuration guidance and drop-in alternative notes that complement the manufacturer's datasheet. Compared to bare Bluetooth modules the LM068 is a finished adapter with connectors and firmware, so its alternatives must also be finished serial adapters in the same form factor, not bare radio modules.
LM509 - Bluetooth 5.4 Dual Mode Class 1 USB Adapter | LM Technologies
The LM Technologies LM509 is a Bluetooth 5.4 dual mode Class 1 USB adapter that provides plug-and-play wireless connectivity for host computers. Housed in an ultra-small form-factor USB dongle, it supports Bluetooth 2.x, 4.x, and 5.x profiles, enabling communication with iOS, Android, printers, keyboards, speakers, and headphones using both Bluetooth Classic (BR/EDR) and Bluetooth Low Energy (LE) radio paths. According to the LM Technologies LM509 datasheet, the adapter is compatible with Linux as well as Windows 10 through Windows 11 host platforms. Background knowledge: Bluetooth dual mode adapters are external peripherals that aggregate a Bluetooth Classic radio (for legacy audio, HID, and SPP profiles) and a Bluetooth Low Energy radio (for modern IoT, beacon, and low-power sensor profiles) onto a single USB endpoint. They are classified as Class 1 when their transmit output power reaches up to +20 dBm and supports an indoor range of roughly 30 meters, which extends coverage well beyond the Class 2 limit (~10 m) used in most laptops. Bluetooth 5.4 itself is a core specification released by the Bluetooth SIG that adds PAwR (Periodic Advertising with Responses), LE-Game-Controller profile support, and encrypted advertisement data, in addition to the 2x throughput and 4x range improvements of Bluetooth 5.0. Key specifications of the LM509 include its dual-mode Bluetooth 5.4 radio, Class 1 transmit power, USB Type-A plug-and-play interface, and OS coverage from Windows 10/11 to mainline Linux kernels. The adapter exposes dual radio paths (BR/EDR + LE) so a host can pair both legacy audio peripherals and modern BLE sensors simultaneously. Bluetooth 5.4 features supported include advertising extensions, periodic advertising with responses, and LE audio metadata. The product is supplied as a finished, end-user-ready module, not a bare silicon IC. Its architecture centers on a Bluetooth 5.4 SoC paired with a Class 1 RF front-end, USB 2.0 device controller, and integrated PCB antenna or external RF chain depending on the SKU variant. The completed enclosure is tested by the manufacturer for EMC and RF conformance, which removes RF tuning work from the integrator. Typical use cases include adding wireless audio and HID connectivity to industrial PCs, providing BLE data uplink for IoT gateways, and acting as a development dongle during Bluetooth firmware bring-up. For successful deployment, verify that the host OS supplies USB HID/Bluetooth enumeration support and that Class 1 radio emissions comply with the regional ETSI/FCC/IC radio regulations at the installation site. The USB bus supplies the device with 5 V at roughly 100 mA, so no external power is required.
LM808 - 433 Mbps Wi-Fi 5 USB Adapter | LM Technologies
The LM Technologies LM808 is a 433.3 Mbps Wi-Fi 5 (802.11ac) USB 2.0 wireless client adapter designed for users requiring high-performance wireless connectivity on desktop and embedded hosts. Built around a Realtek 1T1R (one transmit, one receive) radio chipset, the LM808 fully supports all 802.11 bands including IEEE 802.11ac Draft 2.0 and the legacy 802.11 a/b/g/n specifications, while remaining backward compatible on 802.11n networks. Housed in a compact USB dongle form factor, the LM808 exposes the full 433 Mbps physical-layer rate available on a single spatial stream under 802.11ac, and is paired with a USB 2.0 device interface that draws bus power directly from the host. A Wi-Fi USB adapter is a peripheral module that bridges a host computer's USB bus to a wireless local area network (WLAN). The adapter's internal radio and baseband translate 802.11ac/a/b/g/n OFDM frames into USB packets, allowing any operating system with a generic WLAN driver stack to treat the device as a virtual Ethernet port. Within the wireless-networking taxonomy, the LM808 sits below embedded SiP modules and above raw chip-down radio designs, giving product developers a pre-certified, drop-in connectivity solution without needing to manage antenna matching or RF regulatory compliance themselves. Key features include dual-band 2.4 GHz and 5 GHz operation, Wi-Fi Direct peer-to-peer support for ad-hoc PAN-style networking, 1T1R MIMO, and full USB 2.0 high-speed bus compatibility. The adapter relies on OFDM modulation across the supported 802.11 bands and uses the host's WLAN driver stack to negotiate rates up to 433.3 Mbps. The Realtek-based design has been validated across Windows, Linux, and macOS reference stacks supplied by LM Technologies, removing the need for proprietary driver development. Typical applications include upgrading legacy desktop PCs to dual-band Wi-Fi 5, adding wireless connectivity to industrial PCs and point-of-sale terminals, embedded Linux gateways, retro gaming consoles, and digital signage players. The compact USB-A dongle footprint also makes the LM808 a convenient wireless client for developer boards that lack an on-board Wi-Fi radio, where it can be paired with a Linux host running NetworkManager or wpa_supplicant. When designing with the LM808, verify host-side driver availability for the target operating system and confirm the antenna's radiation pattern is appropriate for the enclosure. USB 2.0 bus-power limits must be observed when designing hubs that will host multiple LM808 adapters in parallel. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes not found in the manufacturer datasheet, providing engineers with a single reference for evaluating the LM808 against competing USB Wi-Fi 5 adapters.
LM813 - WiFi 802.11ac + BT 4.2 Combi Module | LM Technologies
The LM Technologies LM813 is a combination WiFi 802.11ac/a/b/g/n plus dual-mode Bluetooth v2.1/v3.0/v4.2 module delivered as a surface-mount device with an IPEX antenna connector. The module supports WiFi data rates to 433 Mbps and Bluetooth EDR to 2 Mbps (HS mode to 3 Mbps), exposing USB plus GPIO terminals for coexistence signaling in a single compact RF module footprint. A WiFi + Bluetooth combo module is a System-in-Package (SiP) or module-level integration of two radio subsystems (WiFi IEEE 802.11 family and Bluetooth) on a shared PCB, allowing a host processor to add wireless connectivity without designing RF matching networks or managing complex coexistence arbitration in firmware. Combo modules fall within the broader category of RF modules > wireless modules in the connectivity hierarchy. They are commonly deployed when BOM simplification, certified radio performance, and reduced time-to-market outweigh the need for lowest unit cost at scale. Key features of the LM813 include dual-band 2.4 GHz and 5 GHz WiFi operation under the IEEE 802.11ac/a/b/g/n standard family, dual-mode Bluetooth (Classic BR/EDR plus Bluetooth 4.2 LE) for backwards compatibility with legacy audio and data accessories, and an integrated coexistence interface exposed through GPIO pins for arbitration with co-located radios. The module carries an external IPEX/MHF antenna receptacle, allowing antenna selection to be tuned for the end application. The LM813 is built around a combination chipset that implements the 802.11ac MAC/PHY and Bluetooth baseband on a single die. WiFi throughput of 433 Mbps is delivered over a single spatial stream (1x1 SISO) using 802.11ac's mandatory MCS9 modulation, while Bluetooth uses an EDR-capable radio supporting 2 Mbps (HS mode 3 Mbps). The architecture offloads coexistence, channel access, and link-layer management from the host, leaving the host application processor responsible for higher-level networking (TCP/IP, BLE GATT services). Typical applications for the LM813 include industrial IoT edge gateways that need both WiFi infrastructure connectivity and Bluetooth for local provisioning or sensor beacons, point-of-sale (POS) terminals that accept Bluetooth card readers or barcode scanners while joining the store WiFi, and embedded HMI panels requiring over-the-air firmware updates. The dual-band capability also suits consumer audio docks that stream WiFi while maintaining a Bluetooth fallback path. When designing with the LM813, engineers should review the host interface (USB) pin mapping and supply the module from a clean 3.3 V rail with adequate decoupling. Antenna placement and ground keep-out around the IPEX feed line directly affect radiated performance and regulatory compliance. This page synthesizes distributor references, host-interface guidance, and verified parametric data not consolidated in the LM Technologies datasheet.
LM816 - 150Mbps WiFi 4 USB Nano Adapter | LM Technologies
The LM Technologies LM816 is a WiFi 4 (802.11 b/g/n) USB Nano wireless adapter delivering up to 150 Mbps PHY rate, built around a Realtek RTL8188EUS chipset and housed in a compact USB-A dongle form factor. Designed for low-power 5V operation via the USB bus, it supports both ad-hoc and infrastructure mode network architectures and is fully compliant with IEEE 802.11n, b, g, e and i standards including 802.11e QoS and 802.11i security extensions. The integrated chip antenna (IC-ANT) keeps the BOM minimal, making the LM816 well suited to space-constrained host platforms such as single-board computers, industrial gateways, and embedded Linux/Windows devices. A Wi-Fi 4 (802.11n) USB adapter is a peripheral that converts a wired USB host port into a wireless network client operating in the 2.4 GHz ISM band, providing 1x1 SISO throughput up to 150 Mbps and supporting legacy 802.11b/g fallback. In the broader hierarchy, the LM816 sits under wireless LAN adapters -> networking peripherals -> computer interfaces, and uses a single spatial stream with 20 MHz channels and 40 MHz HT capability. This product class is widely adopted for legacy Wi-Fi connectivity on embedded systems where cost, footprint, and driver maturity matter more than the multi-gigabit throughput of newer Wi-Fi 6/6E modules. Key features include hardware-based 64/128-bit WEP, WPA, and WPA2 encryption, soft-AP / Wi-Fi Direct capability, and driver support for Windows, Linux, and macOS hosts. The adapter enumerates as a USB 2.0 high-speed device and uses the standard RTL8188EUS driver tree maintained by Realtek and the Linux community. An internal printed chip antenna (AO/IC-ANT) eliminates the need for an external antenna while preserving the link budget required for typical indoor ranges. The LM816 references the Realtek RTL8188EUS single-chip 802.11n controller, which integrates the MAC, baseband, RF transceiver, and PA on a single die, requiring only an external crystal, EEPROM, and antenna matching network. The 1T1R radio chain, combined with Short GI and MCS7 modulation, enables the headline 150 Mbps PHY rate while staying within USB 2.0 bus bandwidth. This architecture explains the module's low power consumption and small footprint compared to discrete solutions. Typical applications include retrocomputing and embedded Linux SBCs (Raspberry Pi, Toradex, BeagleBone), industrial HMI terminals, point-of-sale systems, digital signage media players, and low-cost retrofit wireless upgrades for older desktops or laptops. The LM816 is also used as a quick evaluation reference for engineers validating 2.4 GHz Wi-Fi link behavior in prototype designs. When integrating the LM816, ensure the host platform provides a USB 2.0 high-speed port with sufficient bus power (typically 500 mA @ 5V). RF performance is sensitive to USB cable length and chassis shielding; for chassis-mounted applications, route the dongle externally to avoid degrading antenna patterns. Verified driver compatibility with the host OS should be confirmed before deployment in production. This page synthesizes distributor pricing, drop-in adapter alternatives, and application notes not found in the manufacturer datasheet, helping engineers select the right Wi-Fi adapter for embedded and industrial deployments.
LM816-USB - 150Mbps Wi-Fi 4 USB Nano Adapter | LM Technologies
The LM Technologies LM816-USB is a Wi-Fi 4 (802.11b/g/n) USB Nano Adapter that delivers up to 150 Mbps data transfer in a compact USB dongle form factor. It is built around a Realtek 8188EUS chipset and is fully compliant with IEEE 802.11 b, g, and n standards, including 802.11e and 802.11i features. The adapter operates in the 2.4 GHz ISM band and supports both ad-hoc and infrastructure network architectures. A USB Wi-Fi adapter (also called a WLAN dongle) is a peripheral that adds wireless networking capability to a host device via the USB bus. It encapsulates the radio, baseband, MAC, and host interface into a self-contained module, allowing embedded systems, single-board computers, and PCs to join Wi-Fi networks without integrating a chipset directly on the motherboard. Within the wireless connectivity hierarchy, USB Wi-Fi adapters sit alongside PCIe Wi-Fi cards, SDIO Wi-Fi modules, and solder-down M.2 WLAN cards as one of the easiest ways to add Wi-Fi to a design. Key features of the LM816-USB include a 1T1R (single transmit / single receive) radio chain, 20 MHz channel bandwidth, and 64/128-bit WEP, WPA, and WPA2 encryption. The adapter is powered directly from the USB 5 V rail, eliminating the need for an external power supply. A reference designator on the product page identifies it as "ADT, 802.11n, USB, 150Mbps, 5V Realtek 8188EUS, Nano". The adapter is pre-certified, which shortens time-to-market for OEMs that would otherwise need to certify a discrete radio. The LM816-USB uses a Realtek RTL8188EUS single-chip 802.11n controller, which integrates the 2.4 GHz radio, MAC, and baseband. The dongle presents a USB 2.0 device to the host and exposes a Wi-Fi station through the standard WLAN NDIS / nl80211 interface on Linux or the Wi-Fi NDIS miniport on Windows. This chipset family is broadly supported by mainline Linux kernels, simplifying driver integration on embedded Linux hosts (note: Toradex lists the LM816 as HCI for Windows CE; embedded Linux support depends on the kernel version in use). Typical applications include adding Wi-Fi to Raspberry Pi or other SBC projects, industrial control panels requiring wireless network access, point-of-sale terminals needing network connectivity, retro computing projects that need network access on legacy hardware, and embedded Linux development boards that lack an on-board Wi-Fi chipset. Its 150 Mbps link rate is sufficient for typical browser, email, and IoT telemetry workloads. When designing with this adapter, consider that the USB connector orientation and dongle clearance must be planned at the chassis level. Because the radio radiates through the dongle body, the USB port should be positioned away from large metal structures that attenuate 2.4 GHz signals. For best throughput, place the host within line-of-sight of the access point and avoid operating near 2.4 GHz interference sources such as microwave ovens and Bluetooth peripherals. This page synthesizes distributor inventory, datasheet specifications, chipset architecture, and application guidance for the LM816-USB, providing practical engineering context beyond what the manufacturer datasheet alone offers.
LM822 - 802.11 b/g/n WiFi Module with IC Antenna, USB HCI | LM Technologies
The LM Technologies LM822 is a WiFi 802.11 b/g/n module operating in the 2.4 GHz ISM band with an onboard chip (IC) antenna and a USB Host Controller Interface (HCI). It supports the IEEE 802.11b, 802.11g and 802.11n standards and delivers data rates up to 150 Mbps on a single stream, packaged as a plug-and-play USB module for OEM integration. What is a WiFi 802.11n (WiFi 4) module? A WiFi 4 (802.11n) module is an embedded radio subsystem that implements the IEEE 802.11n physical and MAC layers and exposes either a host-controlled (HCI) or full-stack (network) interface to the host processor. The LM822 specifically implements HCI over USB, meaning the host CPU runs the network stack and the module acts as a 2.4 GHz radio front-end. These modules sit in the wireless connectivity layer of an embedded system, above the physical RF transceiver and below the application networking stack, and are widely used to retrofit wireless capability into industrial PCs, single-board computers, point-of-sale terminals and gateways. Key specifications of the LM822 per the LM Technologies datasheet include a 150 Mbps PHY rate, BPSK/QPSK/16-QAM/64-QAM modulation, WEP/TKIP/AES plus WPA/WPA2 encryption, a built-in IC antenna (no external antenna or RF connector required), and Linux/macOS/Windows 10 IoT Core/Windows XP to Windows 10/Windows Compact Embedded 6/7 driver support. Compliance with 802.11e bursting and 802.11I standards is also listed. The module draws 5 V through the USB bus and uses the USB port as both the data interface and the power rail. Because all protocol stacks are offloaded onto the host OS (it is HCI-only), the LM822 needs no additional firmware flashing for typical OS environments - it enumerates as a USB WiFi adapter. This makes it well suited to industrial PCs and SBCs that need to add wireless connectivity without a custom driver port. Typical applications include retrofitting WiFi onto legacy industrial PCs, adding wireless connectivity to single-board computers in kiosk and POS designs, embedded gateways that bridge Ethernet to 802.11n WiFi, and Windows Compact Embedded terminals. In each case the LM822's USB HCI and plug-and-play OS driver coverage reduce integration effort compared with bare 802.11 ICs. When designing with this module, note that 2.4 GHz operation only means the host system must coexist with Bluetooth, microwave ovens, and other 2.4 GHz interferers common in industrial and consumer environments. Channel planning and adequate placement of the host PCB relative to metal enclosures is critical because the onboard IC antenna's radiation pattern is shaped by the surrounding ground plane. This page synthesises distributor pricing, a feature comparison with adjacent LM Technologies modules, and practical integration notes that go beyond what the manufacturer datasheet alone covers, helping engineers decide whether the LM822 is the right drop-in wireless module for their embedded platform.
LM823 - WiFi 802.11 b/g/n 150Mbps USB Module | LM Technologies
The LM823 is a WiFi 4 (802.11 b/g/n) USB module from LM Technologies delivering up to 150Mbps wireless throughput at 2.4 GHz with HCI host interface via USB. It is offered in SMT form factor with an IPEX receptacle (u.FL-compatible antenna connector) and operates from a single 3.3 V supply. The module is designed to provide excellent performance with low power consumption while supporting b/g/n standards with full 150 Mbps PHY rate. A WiFi module is a compact radio subsystem that integrates the RF transceiver, baseband processor, MAC, and host interface (USB, SDIO, SPI, or UART) into a single, certified or pre-certified hardware block. It allows a host processor or embedded MCU to add wireless connectivity without having to design the analog RF chain, antenna matching network, or regulatory radio from scratch. WiFi modules are classified by generation (WiFi 4 = 802.11n, WiFi 5 = 802.11ac, WiFi 6 = 802.11ax), by host interface (USB, SDIO, SPI, UART), and by antenna integration (chip antenna, trace antenna, or external antenna via u.FL/IPEX). Key features of the LM823 include IEEE 802.11 b/g/n compliance, 150 Mbps maximum PHY data rate on a 2.4 GHz single-band radio, USB 2.0 HCI host interface, integrated IPEX/u.FL antenna receptacle for flexible external antenna selection, low-power operation, and a compact SMT package for high-density PCB placement. It is shipped in trays of 40 pieces and supports Linux/Android/Windows host drivers commonly available for USB WiFi dongle-class silicon. The module integrates a 2.4 GHz single-band 1x1 SISO radio with 20 MHz channel bandwidth, supporting DSSS/CCK for 802.11b and OFDM for 802.11g/n. Internally it relies on a USB-attached WiFi SoC whose host drivers are widely packaged in mainline Linux kernels, Android, and Windows, so no proprietary firmware porting is required on common host platforms. The IPEX receptacle allows the integrator to swap a higher-gain external antenna for better link margin in metal-enclosed products. Typical applications include embedded Linux gateways, IoT edge nodes, industrial wireless telemetry, point-of-sale terminals, retrofit WiFi for set-top boxes and media players, and USB-attached wireless connectivity for SBCs and developer boards that lack built-in WiFi. The 150 Mbps PHY rate is sufficient for video streaming up to 1080p, VoIP, and bulk file transfer on a local network. When designing with this module, mount the antenna connector area clear of ground copper and tall components to avoid pattern distortion; route the USB D+/D- pair as a 90 ohm impedance-controlled differential pair with matched length. For regulatory compliance, the modular transmitter typically still requires antenna selection and host-integration testing against FCC/CE rules for the final product.

Per the LM Technologies product page and datasheet, the module is offered in multiple SKUs covering tray/IPEX and 2x RF line-out antenna options, all sharing the same WiFi+BT 5.0 silicon foundation. A WiFi + Bluetooth combo module is a small surface-mount or USB assembly that packages a WiFi radio, a Bluetooth radio, an RF front-end, a crystal oscillator, and a host interface (USB, SDIO, or UART) into a single, pre-certified hardware block. This module category sits inside the broader taxonomy of RF modules -> RF transceivers -> wireless connectivity ICs -> semiconductors. By integrating both radios, the module reduces BOM, host-side firmware complexity, and time-to-market for devices that need simultaneous WiFi and Bluetooth coexistence. Key features of the LM843 include dual-band 2.4/5 GHz 802.11ac operation in a 2T2R MIMO configuration, Bluetooth 5.0 dual-mode support (Classic BR/EDR 2.1/3.0/3.0+HS and Low Energy 4.0/4.1/4.2/5.0) with multiple simultaneous Classic+LE connections, USB 2.0 host interface, and on-board power management for maximising throughput across coexisting WiFi/BT links. Hardware is BT 5.0 compliant at the silicon level. Architecturally, the LM843 series uses a 2x2 MIMO WiFi subsystem combined with a Bluetooth 5.0 dual-mode radio sharing a single module PCB and antenna chain through an internal coexistence interface. The USB 2.0 interface carries both WiFi and Bluetooth traffic to the host, simplifying driver bring-up versus SDIO+UART split designs. Typical applications include industrial IoT gateways, wireless POS terminals, set-top boxes and media streaming dongles, USB WiFi+BT adapters, in-vehicle infotainment companion radios, and embedded Linux/Windows host platforms requiring a pre-certified combo radio. Design tip: confirm the exact SKU variant - LM843-8432 (tray, 2x IPEX), LM843-8434 (USB, 2x IPEX), LM843-8438 (tray, 2x RF line-out) - matches the desired host interface (USB vs SMT) and antenna connector (IPEX MHF4 vs RF line-out pad) before PCB layout.

LM845 - WiFi 802.11ac + Bluetooth 4.2 USB Nano Adapter | LM Technologies
The LM Technologies LM845 is a compact WiFi 5 (802.11ac) and Bluetooth 4.2 dual-mode USB nano adapter (dongle) built around a fully integrated single-chip Realtek radio. It operates on the 2.4 GHz and 5 GHz WiFi bands with 1-stream 802.11ac and Multi-user MIMO (MU-MIMO), and it supports Bluetooth v4.2 Dual Mode with backward compatibility to Bluetooth v2.1+EDR and v3.0. Classic Bluetooth and Bluetooth Low Energy (LE) can run simultaneously, enabling concurrent wireless audio/data and BLE beacon use cases over the same USB interface. A WiFi + Bluetooth USB combo dongle is a peripheral that adds short-range wireless connectivity to a host PC, embedded board, or industrial appliance via the USB bus. Inside the dongle, a single radio SoC handles both WiFi (the 802.11 family) and Bluetooth (BR/EDR/LE), sharing one antenna chain through an internal RF front-end. The host sees two logical interfaces (a network interface for WiFi and an HCI interface for Bluetooth) over USB, which simplifies driver integration and shrinks the dongle to a nano form factor that can be left plugged into a laptop or set-top box. Key features of the LM845 include 1-stream 802.11ac Wave-2 operation with MU-MIMO, dual-band 2.4/5 GHz support, Bluetooth 4.2 Dual Mode (BR/EDR + LE) with simultaneous Classic + LE links, a USB 2.0 high-speed host interface, and a Realtek-based single-chip radio that minimizes BOM and power draw. The dongle form factor is sized for always-on installation in laptops, mini-PCs, and industrial HMIs. The internal architecture relies on a Realtek combo MAC/baseband IC with an integrated 2.4/5 GHz PA/LNA chain. WiFi throughput reaches 433 Mbps on the 5 GHz 802.11ac 1x1 link, while Bluetooth supports the standard BR/EDR profiles plus BLE GATT services for IoT pairing and beaconing. Because WiFi and Bluetooth share the same RF chain, the firmware coordinates time-division scheduling to avoid mutual interference. Typical applications include adding dual-band WiFi 5 + Bluetooth to legacy desktop or embedded systems, IoT gateways and industrial PCs that need a quick wireless drop-in upgrade, point-of-sale terminals that pair with BLE peripherals, retrofitted media PCs and set-top boxes that need 5 GHz WiFi for HD streaming, and developer/test rigs that require a stable Realtek-based combo radio for driver qualification. When designing with the LM845, remember that it is a finished USB dongle, not a bare IC: designers cannot change the antenna, regulators, or USB stack. Host drivers must support the underlying Realtek chipset for full 802.11ac + Bluetooth 4.2 functionality, and the host OS USB port must provide enough bus power for the 5 GHz PA under load. This page synthesizes verified distributor information, parametric specifications, and design guidance not consolidated on any single manufacturer or distributor page, including practical notes on host-driver compatibility and concurrent WiFi + Bluetooth operation.
LM848 - Wi-Fi 6 (802.11ax) and Bluetooth 5.2 USB Combo Adapter | LM Technologies
The LM Technologies LM848 is a USB 3.0 combo adapter that integrates Wi-Fi 6 (802.11ax) and Bluetooth 5.2 connectivity through a single USB Host Controller Interface (HCI) port. Designed for embedded Linux, Windows, and Android hosts, the LM848 exposes a high-throughput wireless pipe without burdening the host CPU with baseband firmware, because the dual-mode radio runs the 802.11ax MAC/PHY and the BT 5.2 controller silicon on-module. The USB 3.0 uplink provides the bandwidth required for 2x2 MU-MIMO, 160 MHz channel operation, and OFDMA scheduling features defined in the 802.11ax amendment. A USB combo adapter is a peripheral that bridges a host processor to two or more wireless radios through a standardized serial bus. In the wider connectivity taxonomy, this places the LM848 as a USB peripheral module -> wireless network adapter -> combo radio module -> RF subsystem, sitting beneath the host's network stack and above the antenna. USB-based combo adapters are favored over SDIO or PCIe cards in industrial and prototyping environments because they avoid slot allocation, simplify thermal management, and survive hot-swap events without rebooting the host. The headline features of the LM848 include 802.11ax 2x2 operation, WPA3 security compliance, dual-band 2.4 GHz / 5 GHz / 6 GHz coverage where supported by regional regulations, Bluetooth 5.2 with LE Audio and Long Range (PHY Coded), and a USB 3.0 Type-A form factor that draws bus power. The device advertises ultra-fast throughput that suits video streaming, edge AI gateways, and dense Wi-Fi deployments where 802.11ac throughput would saturate. Architecturally, the LM848 pairs an 802.11ax SoC with a BT 5.2 companion chip, sharing a single USB endpoint group over a USB 3.0 SuperSpeed link. The radio front end is tuned for worldwide regulatory domains, and the firmware exposes standard nl80211/cfg80201 (Linux) and MediaTek/Realtek-style vendor extensions (Windows) for throughput tuning. Typical applications include industrial IoT gateways, in-vehicle infotainment prototyping, point-of-sale terminals, medical telemetry docks, and digital signage where Wi-Fi 6 capacity and Bluetooth coexistence are both required. When designing with the LM848, ensure the host supplies a USB 3.0 port capable of delivering 900 mA, and place the antenna at least 20 mm from any metal enclosure walls to preserve EIRP margin.
LM849 - Wi-Fi 6/BT 5.2 2T2R USB Combo Module | LM Technologies
The LM Technologies LM849 is a dual-band Wi-Fi 6 (IEEE 802.11ax) plus Bluetooth 5.2 combo embedded module in a USB form factor that delivers 2T2R MIMO wireless connectivity for OEM, industrial, medical, scientific, and commercial applications. The module integrates a high-speed host interface compliant with the USB 3.0 specification and remains fully backward compatible with USB 2.0 hosts, supporting 2.4 GHz and 5 GHz simultaneous operation. It is shipped with dual factory antenna configurations supporting either on-board IPEX micro-coaxial connectors or SMT RF line-out pads to suit different mechanical layouts. A Wi-Fi module (also called a wireless module or RF module) is a pre-certified subsystem that integrates a radio transceiver, baseband processor, RF front-end, and host interface on a single PCB, enabling product designers to add wireless connectivity without writing a full driver stack or performing radio compliance testing from scratch. Wi-Fi modules sit at the bottom of the connectivity hierarchy: RF transceiver -> Wi-Fi/BT module -> wireless SoC -> semiconductor, and they are classified by radio technology (Wi-Fi 6 / 802.11ax), host interface (USB / SDIO / PCIe), and supported bands (2.4 GHz / 5 GHz / 6 GHz). Key features of the LM849 include 2x2 MU-MIMO on 802.11ax with up to 1200 Mbps physical layer rate, Bluetooth 5.2 dual-mode (BR/EDR/LE) support, USB 3.0 SuperSpeed host interface, integrated RF shielding, and an industrial operating temperature range suitable for OEM embedded designs. The module is pre-certified in many jurisdictions, which removes a major certification barrier for low-to-medium volume product launches. Typical applications include industrial IoT gateways, point-of-sale terminals, medical telemetry dongles, scientific instrumentation, and commercial wireless display adapters where a USB-attached radio is more practical than an M.2 card. The 2T2R configuration also benefits video streaming and VoIP endpoints that benefit from transmit beamforming and dual-stream receive diversity. When designing with the LM849, confirm the host platform provides sufficient USB 3.0 bus power during radio transmit peaks (typical peak current ~900 mA) and that the chassis antenna path meets the 50 ohm controlled-impedance requirement of either the IPEX connector variant or the SMT RF pad variant.
LM961 - Bluetooth 5.0 Dual Mode Module | LM Technologies
The LM Technologies LM961 is a Bluetooth 5.0 Dual Mode module that combines a Bluetooth Low Energy radio and a Bluetooth v2.0/v2.1 classic radio on a single core with an integrated microcontroller and 8 Mbit flash memory. According to the LM Technologies LM961 datasheet, this module operates as either a GAP Central (master) or GAP Peripheral (slave) device and supports streaming high-quality data while maintaining backward compatibility with Bluetooth v2.0, v2.1, v4.0, v4.1, and v5.0 peers, including iOS and Android hosts. The module is targeted at embedded designs that need a standalone, AT-command-configurable wireless link without requiring an external host MCU to manage the stack. A Bluetooth module is a self-contained subsystem that integrates the radio transceiver, baseband controller, host interface, and sometimes an on-board MCU plus an antenna matching network, exposing a simplified UART/SPI/USB control surface to the host processor. In the broader taxonomy, the LM961 sits within RF modules, which fall under RF & Wireless components, sitting alongside bare RF transceivers, RF amplifiers, and integrated SoCs. Dual mode specifically means the silicon can speak both Classic Bluetooth (BR/EDR) and Bluetooth Low Energy under the same Bluetooth 5.0 stack, which is critical for products that must interoperate with the installed base of classic-only peripherals while also taking advantage of BLE's low-power data channels. Key features include 3 Mbps maximum data rate (BLE 5.0 PHY), embedded Bluetooth dual mode stack, 8 Mbit on-module flash for user application code, and configuration via AT commands in configuration mode. The module supports GAP central and peripheral roles and can establish Bluetooth Low Energy connections in addition to classic SPP/ACL streams. It is designed as a single-core standalone module, meaning the host MCU and the Bluetooth controller share processing on the same die, simplifying hardware design. The architecture pairs an integrated MCU with the Bluetooth 5.0 dual mode core, freeing the application processor from running the Bluetooth stack. Power consumption is dominated by the radio duty cycle, so BLE connection intervals can be tuned for ultra-low average draw in battery-powered products. The 8 Mbit flash allows OEMs to embed application firmware and AT-command scripts directly on the module. Typical applications include industrial IoT gateways, health and fitness wearables, M2M telemetry, point-of-sale terminals, and cable replacement for serial-port legacy equipment. The module is also well-suited for streaming high-quality sensor data over SPP or BLE to iOS and Android tablets. When designing with this device, confirm that the antenna placement keeps the keep-out zone clear of ground pour and that the host PCB provides a clean 3.3 V rail, because TX current spikes directly modulate VCC and degrade RF performance. AT-command configuration requires the host UART to be set to the documented baud rate and flow-control mode.

The industrial-grade M.2 form factor allows easy integration into laptops, tablets, routers, gateways, and ruggedized industrial IoT devices. The M.2 interface carries USB 3.0 / PCIe connectivity, SIM, and GNSS signals over the standard M.2 edge connector, simplifying mechanical design and antenna placement. In practice, the module is used as the WWAN engine behind a host OS driver stack (Windows and Linux drivers are available per 4gltemall documentation listings). Typical applications include mobile computing WWAN cards (the LN940A9 is widely referenced as T77W676 in branded laptop builds), industrial IoT gateways and routers requiring resilient LTE-A backhaul, and networking equipment needing 450 Mbps downlink with 3G fallback. The integrated GNSS receiver supports asset tracking and location-aware services without a separate GPS module. Design consideration: as a cellular module, the LN940A9 requires careful RF layout - keep the M.2 antenna connectors matched to 50 ohm, follow the Telit hardware design guidelines for power sequencing, and budget for module thermal dissipation during sustained uplink transfers. This page synthesizes distributor pricing references, drop-in alternatives, application guidance, and design notes not found in the manufacturer datasheet alone, giving engineers a single citable reference for the Telit LN940A9.

The module measures 14.0 mm x 15.0 mm x 2.8 mm in an LCC-34 surface-mount package with half-through-hole castellated pads for reflow soldering and hand prototyping. A Sub-GHz RF module is a pre-certified, PCB-integrated radio block that combines a transceiver IC, matching network, crystal oscillator, and antenna interface into a single qualified assembly. The LSM100A belongs to the LPWAN (Low-Power Wide-Area Network) module family, sitting below complete SoC transceivers in the wireless connectivity taxonomy and above bare RFICs. It is offered in both AT-command firmware and API firmware variants, where the AT version exposes a serial command interface and the API version exposes the STM32WL firmware APIs for custom application code. Key features include Sigfox RC1 protocol support plus LoRaWAN connectivity simultaneously, ultra-low sleep current for battery-powered deployments, CE / LoRaWAN / Sigfox pre-certification, and an evaluation board (EVBLSM100A) for fast prototyping. The module uses spread-spectrum modulation to deliver ultra-long-range communication with high interference immunity while keeping average current consumption minimal, making it well aligned with metering, asset tracking, and remote sensor applications. The integrated STM32WL SoC provides an ARM Cortex-M4 application core alongside the Sub-GHz radio peripheral, eliminating the need for an external host MCU in many designs. AT-command firmware converts the module into a transparent UART-controlled modem, while the API variant lets integrators load their own firmware into the on-module MCU. This dual-mode capability makes the LSM100A suitable for both quick time-to-market deployments and deeply integrated products. Typical applications include Sigfox RC1 field devices, LoRaWAN end nodes for smart agriculture and utilities, wireless alarm and security sensors, industrial telemetry modems, smart city infrastructure, and battery-powered IoT sensor clusters. The pre-certified RF section removes the most time-consuming compliance step for low-volume product teams. When designing with the LSM100A, ensure the host PCB provides a 50 ohm RF feed to the module antenna pad and adequate clearance under the antenna keep-out area to preserve the radiated performance verified during certification.
LSM110A - LoRa & Sigfox 902-928MHz Hybrid Module | SJIT
The Seong Ji (SJIT) LSM110A is a compact, low-power, bidirectional radio transceiver module for the 902 MHz to 928 MHz sub-1 GHz ISM band, integrating Semtech LoRa and Sigfox modulation technologies in a single FCC-certified LCC-34 package measuring 14.0 mm x 15.0 mm x 2.8 mm.

It is built around an STM32WL series sub-1 GHz SoC, which combines an Arm Cortex-M4 microcontroller with an integrated LoRa radio, eliminating the need for an external MCU in many designs. The module is supplied in both AT-command and API firmware variants, with the API version allowing customer firmware to be integrated directly inside the module. A half-through-hole land pattern allows the LSM110A to be soldered like a standard SMD component onto a simple two-layer carrier board with only a few external passives required. The LSM110A is pre-certified under FCC ID 2BEK7LSM110A, which reduces compliance cost and time-to-market for end products intended for the Americas and Australia. A LoRa (Long Range) radio module is a wireless transceiver sub-system built on Semtech's chirp-spread-spectrum modulation that delivers kilometer-scale communication at very low current consumption, ideal for battery-powered IoT endpoints. Sigfox is a complementary ultra-narrowband LPWAN technology operated by a global network carrier that uses the same sub-1 GHz ISM bands but provides lower bit-rate, longer-range, ultra-low-power messaging. By integrating both protocols, hybrid modules such as the LSM110A let designers choose the optimal transport per packet, geographic region, or application without redesigning hardware. Key features include a high-interference-immunity spread-spectrum physical layer, support for AT and API command interfaces, and FCC pre-certification. The 14.0 x 15.0 mm LCC-34 footprint makes it the smallest LoRa+Sigfox hybrid module in the SJIT portfolio and one of the smallest on the market, allowing product miniaturization for asset trackers and wearable sensor nodes. Architecturally, the STM32WL SoC integrates the radio, modem, and microcontroller into one die, reducing BOM count and PCB area. The LCC-34 package's exposed ground pad improves thermal performance and RF grounding for consistent radiated performance across production lots. Typical applications include Sigfox/LoRaWAN asset tracking, smart agriculture soil and livestock sensors, smart-metering endpoints, industrial SCADA monitoring, and GPS-free indoor/outdoor positioning reference nodes. The hybrid protocol support means a single SKU can ship to the US, Australia, and parts of Asia with no firmware region-locking. When designing with the LSM110A, ensure the antenna matching network is tuned for the specific antenna chosen (chip, trace, or external SMA) and that the host MCU's UART levels match the module's 3.3 V CMOS interface. Power-rail decoupling requires at least a 10 uF bulk plus a 100 nF ceramic placed within 5 mm of the module's VDD pins. This page consolidates distributor pricing, drop-in alternatives from the SJIT LSM family, and practical design notes that are not collated in any single manufacturer datasheet.

The module concurrently tracks GPS, GLONASS, Galileo, and BeiDou constellations across the 1.561 GHz, 1.575 GHz, and 1.602 GHz GNSS bands, delivers a tracking sensitivity of -167 dBm and supports an update/data rate of 921.6 kbps on the UART/USB interface. The MAX-M10S-00B ordering code ships with ROM-based SPG 5.10 firmware on a 500-piece reel. What is a GNSS receiver module? A GNSS (Global Navigation Satellite System) receiver module is an integrated electronic assembly that combines the RF front-end (LNA, SAW filter, mixer), baseband correlator, GNSS processor, and a host interface (typically UART, I2C, or SPI) into a single surface-mount component. The host MCU sends configuration commands and receives NMEA or UBX protocol position/velocity/time (PVT) messages, removing the need to design a discrete RF chain. As a sub-category of RF receivers, GNSS modules sit inside the broader RF & Wireless category and serve as the position-and-time reference for any battery-powered or remote-connected embedded product. Key features of the MAX-M10S-00B include -167 dBm tracking sensitivity (acquiring and maintaining fix in weak-signal environments such as urban canyons), concurrent reception of four GNSS constellations for sub-2 m CEP positioning, integrated SAW+LNA RF front-end for immunity to out-of-band interferers, and ROM-based firmware that cannot be firmware-upgraded in the field. The module also supports both 1.8 V and 3.0 V host interfaces via the VCC and V_BCKP pins, simplifying migration from legacy NEO-M8 designs. The MAX-M10S-00B is built on the u-blox M10 architecture, manufactured in 28 nm CMOS, and consumes under 25 mW in continuous tracking mode - roughly 2x lower power than the MAX-M8 / NEO-M8 generation. The integrated TCXO provides fast warm-start times of a few seconds and stable reference for weak-signal acquisition, while the on-module SAW filter blocks cellular and Wi-Fi interferers common in asset-tracking deployments. Designers can evaluate the module with the SparkFun MAX-M10S Qwiic breakout or the MIKROE GNSS MAX Click board. Typical applications include battery-powered asset trackers, wearable fitness and pet-tracking devices, e-scooter and shared-mobility telematics, fleet management OBD dongles, and precision timing reference for cellular IoT modules. Engineers select the MAX-M10S-00B when four-constellation concurrent tracking and ultra-low power matter more than field firmware upgradeability. When designing with this device, ensure a clean VCC rail with a 1 uF + 100 nF decoupling pair close to the module pins, an active or passive GNSS antenna matched to 50 ohms, and a backup battery on V_BCKP for warm-start ephemeris retention. Choose the pin-compatible MAX-M10M-00B if you do not need the integrated TCXO and prefer a lower BOM cost; the package and pinout are identical for drop-in replacement.
