KSZ8041NL-AM - 10/100 Ethernet PHY, MII/RMII | Microchip
The Microchip Technology KSZ8041NL-AM is a single-supply 10BASE-T/100BASE-TX Ethernet physical layer transceiver (PHY) with MII and RMII media independent interfaces, HP Auto MDI/MDI-X support, and a 32-pin QFN (5x5 mm) package. An Ethernet PHY is the analog/digital interface IC that sits between a MAC (media access controller) in a processor, MCU, or FPGA and the twisted-pair physical cable. In the network stack hierarchy, the PHY occupies the physical layer (Layer 1) beneath the data link layer, performing line coding (4B/5B for 100BASE-TX, Manchester for 10BASE-T), scrambling, equalization, echo cancellation, and clock and data recovery, while also handling auto-negotiation per the IEEE 802.3 standard. Key features of the KSZ8041NL-AM include its single 3.3 V supply operation, which simplifies power tree design in cost-sensitive systems, and its unique mixed-signal design that extends signaling distance while reducing power consumption. The part supports both the parallel MII (16-pin media independent interface) and the reduced pin-count RMII interface, giving designers flexibility when mating to MCUs and embedded processors. HP Auto MDI/MDI-X eliminates crossover cable concerns by automatically selecting transmit/receive pair polarity. Architecturally, the KSZ8041 integrates the 100BASE-TX transmit shaping filter and receive adaptive equalizer and baseline wander correction, minimizing external component count. It requires only standard Ethernet magnetics (a transformer module) plus a 25 MHz crystal reference; note that in RMII mode the KSZ8041NL requires an external 50 MHz clock source per the family hardware design checklist. Typical applications include industrial automation and PLC networking, embedded systems and single-board computers, IP security cameras and networked sensors, set-top boxes and printers, and any MCU/FPGA design requiring a 10/100 Mbps wired Ethernet port. Design consideration: when operating in Auto MDIX mode, Microchip's KSZ8041NL hardware design checklist requires an Auto MDIX-style magnetics module (symmetrical TX/RX channels), and the exposed pad of the QFN must be well-grounded for thermal and EMI performance. This page adds value beyond the datasheet by synthesizing drop-in family alternatives, FAQ coverage of selection and replacement questions, and practical design notes drawn from the manufacturer's errata and hardware design checklist documents.
KSZ8061RNBI - 10/100 Ethernet PHY Transceiver | Microchip
The Microchip Technology KSZ8061RNBI is a single-chip 10Base-T/100Base-TX Ethernet physical layer transceiver (PHY) in a 32-pin QFN (5x5 mm) package designed for data transmission and reception over unshielded twisted pair (UTP) cable. It supports both MII and RMII interfaces for MAC-side connectivity and integrates baseline wander correction plus Quiet-WIRE internal filtering to reduce line emissions for 100Base-TX operation. Operating from a single 3.3V supply, the KSZ8061RNBI delivers industry-standard HP Auto-MDIX for automatic crossover on the differential pairs. An Ethernet physical layer transceiver (PHY) is the lowest layer of the OSI networking model, converting digital MAC-side data into analog signaling across twisted-pair copper media. The PHY implements the IEEE 802.3 physical coding sublayer (PCS), physical medium attachment (PMA), and physical medium dependent (PMD) functions. Within the broader IC taxonomy, the KSZ8061RNBI is a PHY transceiver, a subcategory of Ethernet IC within Communication & Networking ICs, sitting beneath the MAC layer and above the transformer/MDI connector. Key features of the KSZ8061RNBI include HP Auto-MDIX automatic polarity correction, energy-detect power-down modes for system-level power savings, a 25 MHz reference clock input option, and a comprehensive per-pin strap configuration set (PHYAD, ANEN, SNI, etc.) for board-level address and mode selection. The Quiet-WIRE feature set lowers radiated emissions by internal filtering, simplifying automotive and industrial EMI compliance design. Architecturally, the KSZ8061RNBI uses a 3.3V analog core with an internal 1.2V digital LDO plus a DSP-based DSP-PHY receiver for 100Base-TX decoding. Its HP Auto-MDIX logic auto-detects and swaps TX/RX pairs when straight-through or crossover cables are used, eliminating the need for manual crossover and dual RJ45 jacks in most designs. Typical applications include industrial Ethernet nodes, automotive infotainment and gateway ECUs, factory automation controllers, IP security cameras, building automation gateways, and any embedded MCU/MPU board needing a 10/100 Ethernet drop with a small PCB footprint. Its automotive-grade pedigree and Quiet-WIRE filtering make it a frequent choice for CAN-to-Ethernet bridges and telematics control units. One key design consideration is providing a 25 MHz reference clock with appropriate jitter performance, along with a center-tap 1:1 or 2:1 isolation transformer matched to the PHY's analog drive levels. PCB layout must keep the MII/RMII trace lengths matched and the analog supply decoupled with a 10 µF bulk plus 0.1 µF/0.01 µF ceramics close to the AVDD pins. This page synthesizes distributor stock, drop-in alternatives, and design notes not found in the manufacturer datasheet alone. Engineers evaluating the KSZ8061RNBI for a new design will find a compact reference for compliance, replacement options, and PCB integration.

The device integrates two 10/100/1000 Base-T PHYs, a non-blocking store-and-forward switch fabric, and an internal frame buffer suitable for managed-switch applications with QoS and VLAN support. A managed Ethernet switch is a layer-2 networking IC responsible for connecting end devices on the same local area network. Within the broader taxonomy, microchip ISZ9893RNXC-TR falls under Ethernet switch IC -> network interface controller -> communication IC -> semiconductor. These switches typically sit on the same PCB as a host processor (via SPI/I2C/MII/RGMII), handling MAC-layer frame forwarding, address learning, queueing, and traffic classification while offloading these tasks from the application CPU. Key features include support for Energy Efficient Ethernet (EEE), Wake-on-LAN (WOL), Quality of Service (QoS), LinkMD cable diagnostics, and MIB counters for network telemetry. The KSZ9893RNXC-TR is configured via SPI or I2C management interfaces and supports IEEE 802.1Q VLAN, 802.1p priority, and 802.3x flow control. Two of the three ports are full PHY transceivers with HP Auto-MDI/MDIX, while the third port exposes RGMII/MII/RMII to an external MAC or SoC. Architecturally, the KSZ9893R family uses a 1.2 GHz SerDes core for the integrated PHYs, with on-chip termination and adaptive equalization for 1000BASE-T operation over CAT5e cable. The store-and-forward fabric supports 12K-entry address lookup and 4 priority queues per output port. Per-port egress shapers and rate limiting use leaky-bucket algorithms, and the device integrates PTP hardware timestamping for IEEE 1588 applications when configured with external 25 MHz reference. Typical applications include standalone 10/100/1000 Mbps Ethernet switches, VoIP infrastructure switches, Wi-Fi access-point gateways, industrial control switches, broadband gateways, networked measurement and control systems, and security/surveillance systems. The integrated PHY count reduces external magnetics and RJ-45 count, simplifying the BOM for 2+1 + fan managed Gigabit designs. Designers should ensure the 25 MHz reference clock source is within ±50 ppm to meet 1000BASE-T jitter requirements, and follow Microchip reference schematics for the central-tap magnetics and 49.9 ohm termination. The device requires 1.2 V and 3.3 V supplies; both rails should be decoupled with 10 uF + 0.1 uF capacitors near the package. This page synthesizes distributor pricing for the KSZ9893RNXC-TR, drop-in package-compatible variants, and practical design notes not aggregated on any single distributor page, giving engineers a one-stop reference for selecting and laying out this Ethernet switch IC.
LAN8720A-CP-TR - RMII 10/100 Ethernet PHY Transceiver | Microchip
The Microchip Technology LAN8720A-CP-TR is a small-footprint, low-power 10BASE-T/100BASE-TX Ethernet PHY transceiver with an RMII interface to the MAC, housed in a 24-pin QFN (4x4 mm) package. It supports full-duplex 10/100 Mbps operation, HP Auto-MDIX for direct or crossover cable use, and auto-negotiation to select the optimal speed and duplex mode. The device operates from a single 3.3V supply with Microchip's flexPWR technology and provides 1.8V/2.5V/3.3V variable-voltage I/O for direct connection to common MAC ASICs. An Ethernet PHY (physical layer transceiver) is the analog front-end of an Ethernet link, sitting between the RJ-45 magnetics and the MAC controller. It handles line encoding/decoding, clock recovery, link training, and signal shaping so the digital MAC can exchange frames with the network. The LAN8720A belongs to the 10/100 Fast Ethernet PHY family, positioned below Gigabit PHYs in the network interface hierarchy and above purely digital MAC-only designs that require an external analog transceiver. Key features include an integrated 1.2V LDO regulator that can be sourced externally, very low power consumption (claimed up to 40% lower than prior Microchip PHYs), a hardware-strapped configuration for default operation, and commercial temperature grade (0 C to +85 C). The device also includes Energy-Efficient Ethernet (EEE) support and a SMI (Serial Management Interface) for PHY register access. Its 24-pin QFN footprint makes it the industry's smallest 10/100 Ethernet transceiver solution in this package size. Architecture-wise the LAN8720A integrates a 100BASE-TX DSP-based PHY core, ADC/DAC analog blocks, line driver, HP Auto-MDIX termination switches, and a digital control block with MII/RMII muxing. The flexPWR architecture allows the core to run from 1.2V while the I/O rails stay at 1.8V/2.5V/3.3V, eliminating level shifters when paired with most modern SoCs. Power-down and energy-detect modes further reduce quiescent draw for low-power designs. Typical applications include consumer broadband gateways, IP set-top boxes, IP phones, game consoles, industrial Ethernet nodes, and MCU-based designs such as ESP32 ethernet MAC add-on boards where the LAN8720A provides the analog PHY. It is also commonly seen in printers, networked embedded controllers, and small-office routers where space and BOM cost matter more than Gigabit throughput. When designing with this part, select the correct external reference clock (25 MHz) source and place the device close to the RJ-45 jack magnetics to minimize EMI. Verify that the MAC supports RMII (not just MII) and route the 50 MHz RMII reference clock with controlled impedance to avoid jitter. Leave sufficient ground flooding under the exposed pad for thermal dissipation. This page synthesizes distributor stock, drop-in alternatives, design notes and comparison data that go beyond the manufacturer datasheet, helping engineers shorten the LAN8720A-CP-TR selection and validation cycle.

The LARA-R2 architecture pairs a Qualcomm MDM6200/MDM9x07-class baseband with a u-blox-tuned RF front end. Internal signal pull-ups added during the -02B revision (documented in u-blox PCN UBX-17062827) eliminate rare low-temperature diagnostic glitches. The LARA form factor shares pinout compatibility with SARA and TOBY modules, allowing PCB reuse across product families. Typical applications include fleet and asset tracking, point-of-sale terminals, connected health devices, smart metering, industrial telemetry, and alarm/security panels. The AT&T and T-Mobile certifications make drop-in network approval straightforward for North American IoT product launches. The module is also widely adopted for connected vending, EV charging station telemetry, and remote sensor gateways. Designers should size the host PCB clear-out keep-out area below the antenna feed, ensure the SIM card holder is within 10 cm of the SIM pins, and add a TVS diode array on the USB lines for surge protection. For regulatory compliance, the end device must undergo FCC/PTCRB certification with the chosen antenna, even if the module itself is pre-certified. This page synthesizes verified distributor pricing, same-family cross-brand drop-in alternatives, and practical design notes compiled by XAIPART that go beyond what appears in the standalone u-blox datasheet. Sources include DigiKey, Mouser, LCSC, and the official u-blox system integration manual.

A LoRaWAN module is a complete long-range, low-power wireless radio subsystem that integrates a sub-GHz RF transceiver, antenna matching network, and modem firmware on a single certified land-pattern device. Within the LPWA (Low Power Wide Area) connectivity hierarchy, it sits above bare RF chips and below complete end-node systems, letting engineers add km-range telemetry to sensors, meters, and trackers without designing an RF section or navigating radio-equipment certification from scratch. Key features include one of the smallest footprints in the industry for a LoRaWAN module, lower power consumption and higher RF output than previous Murata generations, radio law certification already obtained for major regions, and preloaded modem software for the US915 band that is controlled entirely through simple AT commands. Receiver current is typically 15.5 mA to 20 mA, making the module suitable for coin-cell and battery-powered nodes. At its core the module is built on the Semtech SX1262 LoRa chipset, which provides the LoRa spread-spectrum modulation, high link budget, and up to +21.5 dBm transmit power. Murata integrates the RF front end, crystal reference, and matching network, then validates the design against regional radio regulations so customers inherit a certified RF chain. Typical applications include smart utility metering on US915 LoRaWAN networks, battery-powered asset tracking, smart agriculture sensor nodes, and industrial IoT gateways-to-node links where multi-kilometer range and multi-year battery life are required. For design success, allocate a ground plane under the module, follow the Murata recommended land pattern, and account for the 2 V to 3.6 V supply window - a regulated 3.3 V rail is the natural choice. Antenna is not included on the -296 variant, so plan RF feed and antenna matching on the host PCB. This page synthesizes distributor pricing, firmware-variant comparison (-295 vs -296), and practical design notes not found in the manufacturer datasheet.

An LPWA (Low Power Wide Area) cellular module is a wireless communication subsystem that connects IoT devices to LTE Category M1 (LTE-M) and NB-IoT networks optimized for low data rates, deep coverage, and multi-year battery life. Within the system hierarchy, an LPWA module sits between the host MCU and the cellular antenna, handling RF transceiving, protocol stack execution, and network registration so the host processor only sees an AT command or OpenMCU interface. Key features of the Type 1SC-NTN include the world's smallest Cat. M1/NB-IoT footprint with global certification, seamless Rel-17 NTN satellite connectivity via Skylo technology that requires no hardware design changes, support for GPS/GNSS positioning, an Integrated SIM (iSIM) option, and Murata's OpenMCU capability that lets the module host application code directly. The module operates in the LTE low band (699 MHz to 915 MHz) and mid band (1.71 GHz to 2.025 GHz) and is optimized for 3GPP class 3 output power of +23 dBm. Architecturally, the module comprises an Altair ALT1250 transceiver paired with an FEM (front-end module) and external flash memory, all integrated behind Murata's silver resin shield. This single-package integration minimizes external BOM count, simplifies RF layout, and reduces time-to-market for IoT device makers. Regulatory certifications include FCC/IC, ETSI, and TELEC, plus PTCRB and GCF operator certifications, enabling worldwide deployment on a single design. Typical applications include asset tracking that roams beyond terrestrial coverage, smart utility metering, agricultural and maritime sensors, and fleet telematics where uninterrupted communication - anytime, anywhere - is a requirement. The NTN capability is especially valuable where terrestrial LTE-M/NB-IoT coverage is unavailable or unreliable. When designing with this module, follow Murata's recommended land pattern exactly; datasheet guidance notes that characteristics can vary with land dimensions, NC-terminal grounding method, and PCB material and thickness. Antenna is not included, so plan an external antenna with a 50-ohm matched feed. This page synthesizes distributor availability data, NTN capability details, and practical design guidance not consolidated in the manufacturer datasheet, along with drop-in family alternatives and application pairing recommendations.
LBAD0XX1SC-SFS - LTE Cat M1/NB-IoT Module | Murata
The Murata LBAD0XX1SC-SFS (Type 1SC-SFS) is an LTE Cat M1 / NB-IoT cellular LPWA transceiver module with +23 dBm Class 3 LTE output power, integrated GNSS positioning support, and a compact 11.1 x 11.4 x 1.5 mm (max) silver resin shielded package with LGA-style surface-mount lands. An LPWA (Low Power Wide Area) module is a type of cellular connectivity subsystem that sits within the wireless module hierarchy: transceiver module -> cellular IoT module -> RF & wireless component. LPWA technologies such as LTE-M (Cat M1) and NB-IoT trade peak throughput for dramatically lower power consumption and superior deep-indoor penetration, making them the dominant connectivity choice for battery-powered IoT devices that must communicate over licensed cellular spectrum for 10 or more years on a single battery. Key features of the LBAD0XX1SC-SFS include dual-mode LTE Cat M1 and NB-IoT operation, a user-friendly AT command interface for seamless host integration, and ultra-low-power eDRX and PSM sleep modes that enable 10+ year battery life as stated by Murata. The module integrates the Altair ALT1250 transceiver together with a FEM (front-end module) and external flash memory, so the host board needs only an antenna and minimal external circuitry. On the technical side, the module uses an integrated TCXO (temperature-compensated crystal oscillator) with robust low-drift thermal characteristics, which removes the need for an external oscillator and preserves RF accuracy across the full industrial temperature range. RF coverage spans low and mid LTE bands (699 MHz to 915 MHz and 1.71 GHz to 2.025 GHz per DigiKey listings), and the module is optimized for 3GPP release-compliant Class 3 +23 dBm output power. Murata also highlights support for GPS/GNSS, OpenMCU, Integrated SIM, and NTN (non-terrestrial network) operation in the Type 1SC family. Typical applications include battery-powered smart utility meters, asset trackers, smart-city sensors, and industrial telemetry endpoints where multi-year battery life and global cellular certification (FCC/IC, ETSI, TELEC, PTCRB, GCF) shorten time to market. Design consideration: place the module antenna feed with a controlled 50-ohm trace and follow Murata's recommended land pattern exactly, since the shielded LGA construction relies on the PCB ground plane for RF and thermal performance. This page synthesizes verified manufacturer and distributor data, pricing structure, drop-in family variants, and practical design notes not found in the datasheet alone. Pricing shown reflects availability as of 2026-10-19.
LBAD0XX1WG-EVK-TEMP - LTE Cat M1 Evaluation Kit | Murata
The Murata LBAD0XX1WG-EVK-TEMP is a temperature-qualified evaluation kit for the Type 1WG (LBAD0XX1WG) LTE Cat M1 cellular LPWA module, designed to accelerate development of battery-powered IoT devices that connect over LTE-M networks. The underlying module operates from a 2.85 V to 4.35 V supply, supports receive levels down to -23 dBm, and uses an external antenna configuration, all packaged in a compact LGA-format shielded construction. An LTE Cat M1 module is a cellular LPWA (Low Power Wide Area) modem that implements 3GPP LTE-M protocols, sitting within the broader hierarchy of cellular connectivity: cellular modem -> LTE LPWA module -> wireless connectivity module -> IoT communication device. LTE Cat M1 is optimized for machine-type traffic where ultra-low power, deep coverage, and 10+ year battery life matter more than throughput, distinguishing it from Cat NB1/NB-IoT (narrowband, reduced mobility) and standard LTE (high throughput, high power). Key features evidenced across the Type 1WG/1SC family include 3GPP eDRX and PSM power-saving modes, hibernation power of just 3 uA, eDRX power below 45 uA at 8 hyperframes, and a configurable dormant window in PSM mode. These modes collectively enable the quoted battery life of up to 10+ years for small battery-operated IoT devices. The module family also supports over-the-air (OTA) firmware update, eliminating field-recall costs during deployment. The Type 1SC sibling measures just 11.1 x 11.4 x 1.5 mm and integrates an Altair ALT1250 transceiver, FEM, external flash, and a low-drift integrated TCXO in a silver resin shielded package, indicating the integration density of this product line. Typical applications for this evaluation platform include smart utility meters, asset trackers, smart-city sensors, and industrial telemetry nodes - anywhere a small, battery-operated device must maintain multi-year cellular connectivity. Engineers use the EVK to validate RF performance, characterize current consumption across PSM/eDRX states, and prototype network registration and OTA update flows before committing to custom PCB layouts. When designing with the Type 1WG module, pay close attention to supply-voltage sequencing and current-profile headroom: even though average current is microamps, transmit bursts require the 2.85 V to 4.35 V supply rail to remain stable under pulsed load, so input capacitance and battery internal resistance must be characterized. This page synthesizes verified manufacturer product data, distributor listings, and practical evaluation guidance for the LBAD0XX1WG-EVK-TEMP that is not consolidated on the manufacturer datasheet alone.
LBAD0ZZ2GD-EVK - LTE-M/NB-IoT Cat.M1 Eval Kit | Murata
The Murata LBAD0ZZ2GD-EVK is an evaluation kit for the Type 2GD (LBAD0ZZ2GD) LTE Cat.M1/NB2 cellular IoT module, an ultra-small, ultra-low-power LPWA module that integrates the LTE SoC, RF front end, crystal, and SRAM and flash memory in a compact LGA package. The kit enables engineers to prototype, test, and certify 3GPP Rel-14 LTE-M and NB-IoT connectivity before committing to a custom PCB design. An LPWA (Low Power Wide Area) module is a type of cellular communication module belonging to the broader hierarchy of connectivity module -> RF module -> IoT communication device. LTE Cat.M1 (LTE-M) and NB-IoT are licensed-band 3GPP standards designed for battery-powered IoT devices that prioritize minimal cost and power consumption over throughput; LTE-M provides approximately 1 Mbps upstream and 1 Mbps downstream, and both standards support mobility, making them suitable for moving devices with reduced radio interference compared with unlicensed-band solutions. Key features of the underlying LBAD0ZZ2GD module include 3GPP Rel-14 compliance, dual-mode LTE-M/NB2 operation, 8 MByte of flash memory, and low-power modes including PSM (Power Saving Mode) and eDRX (extended Discontinuous Reception). Murata states its compact LPWA module family achieves power consumption as low as 1.5 uA in Power Saving Mode, which is a central reason for selecting this platform for battery-powered designs. The module uses an external antenna configuration and an LGA surface-mount land pattern per Murata standard recommendations. Technically, the Type 2GD integrates the complete signal chain on a single substrate: the LTE SoC handles baseband and protocol processing, the RF front end drives the external antenna, and integrated SRAM and flash eliminate external memory BOM items. Because the RF front end, crystal, and memory are pre-integrated and pre-tested, designers avoid the most difficult RF layout tasks and inherit Murata's certification baseline, with the module carrying FCC ID HSW-TY2GD via Murata Electronics North America. Typical applications evaluated with this kit include smart utility metering, asset tracking, smart city infrastructure, industrial sensors, and battery-powered telemetry nodes. The evaluation kit lets developers exercise PSM/eDRX duty cycles and measure real current profiles before finalizing the power budget. A key design consideration: Murata's datasheet notes that module characteristics vary depending on land pattern drawing method, grounding method, land dimensions, NC-terminal land forming, and PCB material and thickness, so the EVK-provided reference layout should be followed closely when transitioning to production. This page synthesizes distributor data, verified web sources, and practical integration guidance for the LBAD0ZZ2GD-EVK not consolidated in the manufacturer datasheet.

Per the manufacturer datasheet, the module delivers up to 433 Mbps PHY on Wi-Fi and 3 Mbps PHY on Bluetooth, with an integrated dual-band RF chain, crystal, power-management circuitry, and shielding in a compact SMD footprint suitable for space-constrained IoT and embedded designs. A Wi-Fi + Bluetooth combo module is a pre-certified subsystem that bundles the radio transceiver, baseband processor, antenna matching network, and regulatory shielding into a single reflow-solderable component. The module sits between the host application processor (which runs the network stack and BT profiles) and the wireless air interface, offloading RF complexity, FCC/ETSI/TELEC certification burden, and BOM risk. The Murata Type 1MW family specifically targets low-power IoT endpoints that need modern dual-band Wi-Fi and Bluetooth 5.0 coexistence without discrete RF design effort. Key features of the LBEE5HY1MW-230 include dual-band 2.4 GHz and 5 GHz operation with 802.11ac wave-2 (433 Mbps), Bluetooth 5.0 with LE 2M PHY and LE Coded PHY support, integrated shield and reference clock, and an SDIO 3.0 + UART host interface. The SMD package is reflow-compatible at standard 260 °C peak profile, and antenna is not included (typical for modules with host-board antenna or external antenna pigtail). Operating temperature is rated for industrial -30 °C to +85 °C environments. Architecturally, the module integrates the Infineon CYW43455 die, a 37.4 MHz reference crystal, RF matching network, transmit balun, low-noise PA chain, and DC-DC regulators on a multilayer ceramic substrate with metal shield. Wi-Fi and Bluetooth radios share an antenna diversity topology with internal coexistence arbitration, allowing simultaneous 2.4 GHz WLAN + BT operation with on-chip packet scheduling. The module presents a standard SDIO 3.0 interface to the host MCU/MPU for WLAN and a 4-wire UART (plus PCM for BT audio) for Bluetooth. Typical applications include Wi-Fi 5 + BLE smart-home gateways, industrial IoT gateways, wireless POS terminals, audio streaming products (BT classic A2DP + Wi-Fi), medical telemetry devices, and consumer electronics that need modern dual-band connectivity without in-house RF expertise. The integrated shield dramatically simplifies EMC compliance at the end-product level. When designing with the LBEE5HY1MW-230, allocate a keep-out zone under the antenna feed, provide a clean 3.3 V rail with adequate bulk decoupling, and follow Murata's reference layout for the host-board antenna or pigtail. Host-driver selection (Linux/Backport, Android HAL, or vendor-specific MCU port) is critical - confirm firmware compatibility before committing to the design.

LBES0ZZ2FR-580 - Wi-Fi 6 + BT 5.4 + 802.15.4 Module | Murata
The Murata LBES0ZZ2FR-580 is a Type 2FR multi-radio SMD transceiver module based on the NXP RW612 combo chipset, supporting IEEE 802.11a/b/g/n/ac/ax (Wi-Fi 6) dual-band, Bluetooth LE 5.4, IEEE 802.15.4 (Thread/Zigbee), and Matter smart-home connectivity in a single, highly integrated 140-pin surface-mount package. A Wi-Fi + Bluetooth module is a pre-certified radio subsystem that combines an RF transceiver, baseband processor, and integrated antenna or RF trace on a single PCB. These modules dramatically reduce BOM count, FCC/CE/TELEC certification cost, and PCB complexity by abstracting the radio hardware and presenting a host MCU interface. The Type 2FR sits in the module product hierarchy between simple Wi-Fi-only modules and full SoC platforms, and is widely adopted in connected smart devices, enterprise and industrial automation, smart accessories, and smart-energy endpoints. Dual-band 2.4 GHz and 5 GHz operation plus 802.15.4 makes it a true multiprotocol gateway IC for Matter, Thread, and Zigbee ecosystems. Key features include dual-band 2.4 GHz and 5 GHz Wi-Fi 6 (802.11ax) operation, Bluetooth LE 5.4 with long-range and direction-finding support, integrated 802.15.4 radio for Thread and Zigbee, an integrated high-performance Arm Cortex-M33 application MCU with advanced security (secure boot, crypto accelerators, TrustZone-M), a supply voltage range of 3.14 V to 3.46 V (typical 3.3 V), output power from 12 to 18 dBm, and receive sensitivity down to -104.7 dBm depending on modulation. The surface-mount LGA-style module ships tape-and-reel and is lead-free. The RW612 silicon inside combines a Wi-Fi 6 MAC/PHY, Bluetooth 5.4 LE radio, and 802.15.4 PHY on a single die with an internal PA, LNA, and RF front-end. Murata integrates the chipset, crystal, RF matching, and shielding into a module that is pre-certified for major regulatory domains, eliminating the customer's RF design risk and antenna tuning effort. The on-die Cortex-M33 host allows bare-metal or RTOS firmware to run directly on the module, removing the need for an external host MCU for many IoT edge applications. Typical applications include Matter-compatible smart-home hubs, Thread border routers, Wi-Fi/BLE smart appliances, industrial IoT gateways, asset-tracking sensors, and connected lighting controllers. The dual-band Wi-Fi 6 capability is particularly valuable in congested environments where 2.4 GHz-only devices suffer interference from neighboring Wi-Fi networks, microwaves, and Bluetooth peripherals. When designing with this module, follow Murata's reference layout and grounding recommendations exactly. The RF trace routing, decoupling placement, and host-interface pin mapping are pre-engineered; deviating from the reference design will degrade RF performance and may void regulatory certifications. Use the recommended host-driver SDK from NXP/Murata to leverage the integrated MCU and radio coexistence features.
LBEU5ZZ1WL-633EVB - LoRaWAN GNSS BLE Wi-Fi Eval Board | Murata
The Murata LBEU5ZZ1WL-633EVB is an evaluation board for the Type 1WL (LBEU5ZZ1WL-633) multi-technology fused LoRaWAN geolocation module, which combines Semtech LR1110 LoRa/Wi-Fi/GNSS scanning, a STMicroelectronics STM32WB55VGY6 wireless MCU, and an Airoha MT3333AV high-performance GNSS receiver in one platform for developing low-cost IoT tracking devices. An LPWAN geolocation module is a type of wireless connectivity module that fuses long-range low-power radio (LoRaWAN) with multiple positioning technologies (satellite GNSS, Wi-Fi access-point scanning, and GNSS scanning). Within the system hierarchy, it sits above individual transceivers and below complete end products, providing a pre-certified radio subsystem for asset tracking, telemetry, and industrial IoT nodes. Key features include ultra-low power design: the internal MCU draws only 4.7 uA typical in stop2 mode with RTC running while the LR1110 and MT3333 are off, per the Type 1WL datasheet (Rev. D, VDD = 3.3 V, 25 C). Wireless coverage spans LoRa sub-GHz, Wi-Fi 802.11b/g/n at 2.4 GHz, Bluetooth v5.2, and GNSS including GPS and BeiDou. The STM32WB55 provides an ARM Cortex-M4 core with 256 KB RAM and 1 MB Flash, plus a USB 2.0 full-speed interface that is USB-IF certified. Technically, the module fuses three positioning engines: LR1110 Wi-Fi and GNSS scanning delivers indoor/outdoor fixes without acquiring full satellite signals, the MT3333AV provides standalone high-performance GNSS, and LoRaWAN uplink transports position and telemetry to network servers such as those used by Abeeway-based tracking solutions. The evaluation board exposes the module interfaces, antenna connections (antenna not included on the module), and USB connectivity for rapid prototyping. Typical applications include battery-powered asset trackers for logistics, industrial equipment monitoring, indoor/outdoor personnel and livestock tracking, and smart-city IoT sensors that need multi-year battery life. The 4.7 uA sleep current enables designs that run for years on a primary lithium cell. Design consideration: budget antenna selection and RF layout early, since the module ships without an antenna and GNSS/Wi-Fi/LoRa performance depends heavily on placement and ground-plane design. This page synthesizes distributor availability, datasheet-derived specifications, and practical design notes not found in the manufacturer datasheet alone.
LBUA0VG2BP-741 - NXP SR150 UWB Transceiver Module | Murata
The Murata Electronics LBUA0VG2BP-741 is an ultra-small Ultra-Wideband (UWB) module, the Murata Type 2BP, which integrates the NXP SR150 UWB chipset together with clock, filters, and peripheral components in a surface-mount package with antenna not included. It is a multiprotocol RF transceiver module implementing IEEE 802.15.4 UWB communication for precision ranging and secure fine-ranging applications. An Ultra-Wideband module is a short-range radio transceiver that transmits data across a very wide spectrum (several gigahertz of bandwidth) at very low power density. Within the wireless-connectivity hierarchy, UWB sits alongside Bluetooth Low Energy, Zigbee, and Wi-Fi as a personal-area-network technology, but it is distinguished by time-of-flight measurement capability, which enables centimeter-level distance and positioning accuracy that narrowband radios cannot achieve. Key features of the LBUA0VG2BP-741 include the integrated NXP SR150 UWB chipset, onboard clock and filtering, channels 9 support, low current consumption, and a compact, high-quality form factor. DigiKey lists the part as an 802.15.4 UWB transceiver module, surface mount, antenna not included, allowing designers to select an antenna optimized for their enclosure and region. The module architecture offloads RF design complexity from the customer PCB, since matching networks and sensitive RF routing are already engineered inside the certified module. Technically, the module builds on the NXP SR150, which implements ultra-wideband impulse-radio signaling compliant with the IEEE 802.15.4z-era UWB physical layers used in FiRa-class ranging. Time-of-flight and angle-related measurements are performed between compliant devices for secure keyless entry, asset tagging, and indoor positioning. Because the SR150, crystal clocking, and RF filters are pre-integrated, the host MCU communicates over a digital interface, dramatically reducing certification and RF-tuning effort compared with a discrete chipset design. Typical applications include UWB keyless-entry systems for automotive and access control, real-time location systems (RTLS) and indoor asset tracking, secure contactless payment and device-to-device ranging in IoT devices, and drones or robotics requiring precise relative positioning. Its low current consumption and small size make it well suited to battery-powered tags and compact sensor nodes. Design consideration: since the antenna is not included, antenna selection, feed-line layout, and placement directly affect conducted performance and regulatory compliance; follow the Murata Type 2BP specification document for recommended antenna and layout guidance. This page synthesizes distributor listings, availability signals from seven distributors via Octopart, and design context not found in the manufacturer specification sheet alone. Pricing tiers are marked as needing verification as of 2026-10-20.

An Ultra-Wideband module is a short-range, high-precision RF transceiver that transmits narrow pulses across a wide spectrum, enabling centimeter-level ranging and secure fine-ranging. Within the wireless connectivity hierarchy, it sits alongside BLE, Wi-Fi and GNSS as a radio module, and combo modules such as this integrate both the UWB PHY and a companion short-range radio plus host MCU on a single certified, pre-tested footprint, dramatically reducing RF design effort compared with discrete chipsets. Key features include the NXP Trimension SR040 UWB chipset for IEEE 802.15.4z-class fine ranging, the NXP QN9090 Bluetooth LE and ARM Cortex-M4-based MCU for application processing, and an integrated antenna with matching components and crystals already on-board. This all-in-one integration means developers avoid antenna tuning and RF layout iterations, achieving regulatory radio certification with a single module. Technically, the module combines two independent radio chains: the SR040 handles UWB channel access in the 6.25-8.25 GHz band used for secure distance bounding, while the QN9090 provides Bluetooth v5.0 LE connectivity for provisioning, data backhaul and device-to-device communication. Low-power design supports coin-cell battery operation, which is central to the tag and tracker use case. Typical applications include UWB tags and trackers, smart-door locks and access control, indoor positioning and asset tracking in factories and hospitals, and general IoT devices that need precise ranging plus a BLE control link. A key design consideration is power budgeting: UWB ranging sessions dominate energy consumption, so duty-cycle the UWB radio and rely on BLE for standby communication to maximize coin-cell life. This page synthesizes distributor inventory data, drop-in alternative analysis, and practical design notes not found in the manufacturer datasheet, verified as of 2026-10-20.
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. This page synthesizes distributor pricing, cross-reference findings, and design guidance not consolidated in the manufacturer datasheet.
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. This page synthesizes verified manufacturer and distributor data, drop-in alternatives, engineering design notes, and FAQ content not found together in the product brief.
LBWA0ZZ2HL - Sub-1GHz Wi-Fi HaLow 802.11ah Module | Murata

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.
LC29D - Dual-Band GNSS Module with RTK/DR | Quectel
The Quectel LC29D is a concurrent multi-constellation GNSS receiver module operating on dual GNSS bands (L1+L5), integrating a 6-axis inertial sensor fused with RTK and dead-reckoning algorithms to deliver sub-meter positioning accuracy in open-sky environments. Housed in a compact 12.2 mm x 16.0 mm x 2.4 mm LCC package weighing 0.9 g, the LC29D supports concurrent tracking of GPS, GLONASS, IRNSS, BeiDou, Galileo and QZSS constellations, with the BCM47758 chipset enabling high-precision positioning. A GNSS (Global Navigation Satellite System) module is a satellite-receiving electronic component that computes position, velocity and time (PVT) solutions by trilaterating ranging signals from multiple satellite constellations. The technology hierarchy spans: GNSS module -> satellite receiver -> positioning IC -> RF receiver -> wireless semiconductor. Modern multi-band GNSS modules like the LC29D differ from single-band L1-only receivers by simultaneously tracking the L5 band, which provides higher chipping rate, better multipath mitigation, and improved robustness against ionospheric delay, directly translating into centimeter-to-decimeter level accuracy when paired with RTK corrections. Key features include sub-meter positioning accuracy under open sky, concurrent multi-constellation reception across six satellite systems, integrated 6-axis IMU for sensor-fusion dead-reckoning, and RTK support for centimeter-level corrections. The module supports both LCC and LGA package variants and operates over an extended industrial temperature range, making it suitable for automotive and industrial tracking. Technically, the LC29D uses Broadcom's BCM47758 dual-band GNSS engine, which can output RTCM 3.x correction data and supports PPP (Precise Point Positioning). The integrated IMU enables dead-reckoning to maintain accurate positioning during GNSS outages in tunnels, urban canyons, and parking structures, while RTK support achieves centimeter-level accuracy when correction streams are available. Typical applications include vehicle tracking and fleet management, shared mobility (e-scooter, e-bike, ride-share), asset tracking, precision agriculture, and ADAS platforms. The module's RTK capability makes it well-suited for drones, autonomous robotics, and surveying equipment requiring centimeter-level accuracy. When designing with the LC29D, ensure the host processor can provide RTCM correction data over UART or IP connection for full RTK operation. Route the RF input trace with controlled impedance and place the antenna as far from noise-generating circuitry as possible to maximize CN0. Use the recommended L1+L5 stacked patch or active multi-band antenna. This page synthesizes verified distributor pricing, parametric same-family LC29D variants, and practical RF layout design notes that go beyond the Quectel datasheet, giving engineers a single, citation-ready reference for product selection.
LC79DAEK - LC79D GNSS Evaluation Board Kit | Quectel
The Quectel LC79DAEK is an evaluation board kit (EVB) for the Quectel LC79D multi-constellation GNSS positioning module, designed to accelerate hardware integration and firmware bring-up. The kit exposes the LC79D module's L1+L5 dual-band GNSS receiver, antenna interface, USB/UART communication ports, and power input on a ready-to-use PCB that hosts an integrated LNA and SAW filter chain. A GNSS (Global Navigation Satellite System) module is a radio receiver that simultaneously tracks signals from multiple satellite constellations (GPS, GLONASS, Galileo, BeiDou, QZSS, NAVS) to compute position, velocity and time (PVT). GNSS modules belong to the broader RF receiver category and sit in the hierarchy: GNSS module -> satellite navigation receiver -> RF receiver -> wireless transceiver -> semiconductor. They typically integrate an RF front-end, baseband processor, and a positioning engine that outputs NMEA-0183 or proprietary binary protocols over UART/USB. Key features of the LC79DAEK include support for GPS L1+L5, GLONASS L1, Galileo E1+E5a, BeiDou B1I+B1C+B2a, QZSS L1+L5 and SBAS, achieving centimeter-level convergence with RTK corrections. The EVB integrates a high-gain LNA, SAW filter for out-of-band rejection, active antenna power supply, and an on-board USB-to-UART bridge for direct PC connection. Operating voltage spans 3.0 V to 5.5 V, and the board exposes standard 2.54 mm headers for all I/O. Typical applications include autonomous-robot localization, asset-tracking telematics, precision-agriculture GNSS receivers, surveying and mapping devices, and unmanned-aerial-vehicle (UAV) navigation. The dual-band L1+L5 architecture delivers robust multipath rejection in urban canyon environments, which is essential for ADAS and lane-level mapping. Compared to single-band L1-only GNSS modules, the LC79D's L5 reception improves position accuracy from ~2.5 m to ~0.5 m in open-sky conditions. When designing with the LC79DAEK, ensure the active antenna bias-tee supplies 3.0 V to 5.5 V at the LNA feed, and that the USB-to-UART bridge is configured for 115200 bps 8N1 by default. Place the EVB away from switching power converters and large digital buses to minimize GNSS in-band interference.
LC79DBEK - Quectel LC79D GNSS Evaluation Board Kit | EVB
The Quectel LC79DBEK is an evaluation board (EVB) kit for the Quectel LC79D multi-GNSS positioning module, supplied in a developer-ready kit format that exposes all functional pins, an on-board active antenna interface, USB/UART bridges, and reference power rails. The kit is intended to accelerate prototyping of LC79D-based designs that require concurrent GPS, GLONASS, Galileo, BeiDou, QZSS and SBAS reception, with positioning performance validated per AIS-140. The LC79D module at the heart of the kit is a multi-constellation GNSS receiver module that integrates a 28nm GNSS chipset, on-board LNAs and SAW filters, and an advanced low-power management solution. A GNSS receiver module is a satellite-radio receiver that calculates its own 3-D position, velocity and time by trilaterating ranging signals from multiple Medium Earth Orbit (MEO) and Geosynchronous (GEO) satellites; in the broader taxonomy, GNSS modules sit under satellite-positioning receivers, then radio-frequency receivers, then wireless modules, then electronic modules. Quectel's LC79D family targets fleet telematics, vehicle tracking, asset monitoring and AIS-140-compliant in-vehicle systems. Key features of the development kit include direct access to UART, I2C and PPS interfaces, integrated SMA connector for active GNSS antenna, USB-to-UART bridge for direct PC connection, status LEDs for power and 1PPS, and a regulated 3.3V reference supply. The on-module LNAs and SAW filters harden acquisition against weak-signal and jamming-rich environments, which is critical for aftermarket vehicle installations and metal-shielded telematics enclosures. The LC79D module uses 28nm CMOS process technology, enabling the low power consumption that battery-powered asset trackers require. Multi-constellation concurrent operation shortens time-to-first-fix (TTFF) and improves position accuracy in urban canyons, where single-constellation receivers suffer frequent dropouts. The module is AIS-140 compliant, an Indian automotive telematics standard that mandates specific update rates, accuracy and security features for commercial vehicles. Typical applications include AIS-140-compliant vehicle tracking units, fleet management telematics, e-call and ERA-GLONASS-style emergency call systems, two-wheeler telematics boxes, asset tracking and cold-chain monitoring, and shared-mobility scooter trackers. The evaluation kit accelerates bench validation before committing to a custom LC79D carrier PCB layout. When designing with this kit, always use the included active LNA antenna in the SMA port for first-time verification; passive antennas will yield degraded CN0 figures and longer TTFF. Ensure host firmware drives the LC79D's on/off and reset pins per the LC79D GNSS specification rather than relying solely on supply-rail cycling, since the module's backup-domain logic requires a controlled shutdown sequence to preserve ephemeris.

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.
