BLE112-A-V1C - BLE 4.0 Module with U.FL Antenna | Silicon Labs
The Silicon Labs BLE112-A-V1C is a Class 2 Bluetooth Smart (Bluetooth v4.0 single mode) module with a U.FL antenna connector, operating in the 2.4 GHz ISM band at data rates up to 2 Mbps from a 2 V to 3.6 V supply on a 32-pin SMD module footprint. It is the external-antenna variant of the Bluegiga BLE112 family, targeted at low-power sensors and wireless accessories. A Bluetooth Low Energy module is a complete wireless subsystem that integrates a BLE radio, a microcontroller, an antenna or antenna connector, and a certified protocol stack into a single surface-mount package. Within the wireless hierarchy, it sits below full Bluetooth systems and above bare radio chips, allowing designers to add BLE connectivity without developing RF layout, antenna matching, or regulatory certification themselves. Key features include Bluetooth v4.0 single-mode compliance, support for both master and slave roles with 4 or more simultaneous connections in master mode, and an integrated Bluetooth Low Energy stack covering GAP, GATT, L2CAP, SMP, and BLE profiles. The fully integrated approach combines radio, microcontroller, and software stack in one certified module, dramatically reducing development effort. Technically, the module integrates the BLE radio transceiver with an on-board microcontroller running the Bluegiga Bluetooth Smart software, so host processors can communicate over a simple interface or the application can run entirely on-module. The U.FL connector permits an external antenna for optimized range and enclosure flexibility, distinguishing the -V1C variant from the chip-antenna BLE112-A-V1. Typical applications include battery-powered sensor nodes, proximity beacons, fitness and health accessories, and industrial wireless monitoring where a Class 2 link with an externally optimized antenna is preferred. The 2 V to 3.6 V supply range allows direct operation from a coin-cell battery. Design consideration: the U.FL variant requires a mating antenna assembly (U.FL to SMA pigtail plus antenna) in the bill of materials, and the 50-ohm transmission line to the connector should follow controlled-impedance layout practice on the host PCB.

BLE112-E-V1 - Bluetooth 4.0 BLE Module U.FL | Silicon Labs
The Silicon Labs BLE112-E-V1 is a Bluetooth v4.0 single-mode Bluetooth Low Energy (BLE) transceiver module operating in the 2.4 GHz ISM band, offering 2 Mbps over-the-air data rate, -91 dBm receiver sensitivity, and a supply voltage range of 2.0 V to 3.6 V. The E-version variant features a U.FL RF connector for an external antenna, in a surface-mount module package, and is classified as a Bluetooth Class 2 device. A Bluetooth Low Energy module is an integrated wireless subsystem that combines a 2.4 GHz radio transceiver, a microcontroller, an antenna feed, and a complete BLE software stack on a pre-certified printed circuit assembly. Within the wireless connectivity hierarchy, it sits below full custom radio designs (lower integration effort) and above bare wireless MCUs (higher ease of use), making BLE modules the fastest route to adding short-range, ultra-low-power connectivity to a product. Key features of the BLE112-E-V1 include full Bluetooth 4.0 single-mode compliance, an integrated radio, microcontroller and software stack in one package, an 18-source interrupt controller, and support for power modes 1 and 2 in which the sleep timer keeps running to minimize average current draw. The module is targeted specifically at low-power sensors and accessories where battery life, not throughput, is the primary design constraint. Technically, the module is built around the CC2540 Bluetooth SoC, which pairs an industry-standard 8051 core with a 2.4 GHz RF transceiver. Peripheral peripherals can choose between two alternate I/O pin locations for layout flexibility, and an ultra-low-power sleep timer uses an external 32.768 kHz crystal oscillator. Receiver sensitivity of -91 dBm provides practical indoor range for a Class 2 device, while the 2 Mbps PHY minimizes radio-on time. Typical applications include battery-powered sensor nodes and beacons, wireless health and fitness accessories, smart-home sensor peripherals, and RS232-over-BLE cable replacement links in industrial equipment. When designing with the BLE112-E-V1, plan the power budget around sleep modes and remember that the E variant requires an external antenna connected via the U.FL receptacle; the -A variant integrates the antenna on the PCB instead. Supply rails must stay within 2.0 V to 3.6 V, ideally from a primary lithium or single Li-Ion cell.

BLE113-A-M256K - Bluetooth 4.0 BLE Module 256K Flash | Silicon Labs
The Silicon Labs BLE113-A-M256K is a Bluetooth Smart (Bluetooth v4.0 low energy) transceiver module operating at 2.4 GHz with an integrated chip antenna, 256 KB flash memory, a supply range of 2.0 V to 3.6 V, 2 Mbps over-the-air data rate, and -93 dBm receiver sensitivity. It is a fully integrated Bluetooth Smart solution combining the radio, a microcontroller, and the Bluetooth software stack in a single surface-mount module. A Bluetooth Low Energy (BLE) module is a complete wireless subsystem within the broader hierarchy of RF transceiver modules and short-range wireless communication devices. Whereas a bare radio chip requires the designer to integrate a microcontroller, antenna matching network, and protocol stack, a BLE module such as the BLE113 integrates all features required for a Bluetooth smart application: the Bluetooth radio, antenna, MCU, and certified stack, reducing time to market and RF design risk. Key features include the 256 KB flash variant (versus 128 KB on BLE113-A-V1), which is significant for over-the-air (OTA) firmware updates and extensive BGScript applications, integrated chip antenna eliminating external RF matching design, and low power operation targeted at small sensors and accessories. Serial interfaces include ISP, PWM, SPI, and UART, allowing flexible host connectivity or fully standalone operation via BGSCRIPT. Technically, the module is built around the Texas Instruments CC2541 utilized IC and belongs to the Bluegiga BLE113 family acquired by Silicon Labs. The -93 dBm sensitivity supports reliable connections at Class 2 power levels on the 2.4 GHz ISM band, and the integrated antenna means the RF performance is pre-certified, saving regulatory test cost. Typical applications include low-power sensors and accessories, battery-powered health and fitness devices, beacons, smart home endpoints, and industrial wireless sensor nodes where a compact, certified BLE link is required. A key design consideration is supply voltage: the module accepts only 2.0 V to 3.6 V, so a single CR2032 coin cell or a regulated LiPo rail works well, but 5 V systems require an LDO. Allow antenna keep-out clearance on the PCB around the chip antenna region.

BLE113-A-V1 - Bluetooth 4.0 BLE Module, 2V-3.6V | Silicon Labs
The Silicon Labs BLE113-A-V1 is a Bluetooth Smart (Bluetooth 4.0 low energy) transceiver module operating in the 2.4 GHz ISM band from a 2.0 V to 3.6 V supply, with a receive sensitivity of -93 dBm and an integrated chip antenna in a compact 28-pad surface-mount castellated package. Originally developed by Bluegiga Technologies, later acquired by Silicon Labs, it targets small, low-power sensors and accessories. A Bluetooth Low Energy (BLE) module is a complete short-range wireless subsystem that integrates the 2.4 GHz radio transceiver, a microcontroller, the BLE software stack, and an antenna into a single certified unit. Within the connectivity hierarchy (module -> BLE radio -> 2.4 GHz transceiver -> RF IC -> semiconductor), modules eliminate the RF design, regulatory certification, and stack porting work otherwise required of a discrete chip design. Key features of the BLE113 include a fully integrated Bluetooth radio, microcontroller, and GATT-based software stack; the ability to host the end-user application on-module via the BGSCRIPT scripting language or BLE API, so no external MCU is needed in size- or price-constrained devices; serial interfaces including UART, SPI, PWM, and ISP for system integration; and very low power consumption for battery-powered designs (active-mode current is roughly 6 mA per Silicon Labs community measurements on comparable firmware). Architecturally, the module is built around the Texas Instruments CC2541 BLE system-on-chip running the Bluegiga iWRAP-based Bluetooth Smart stack. The GATT profile server and client, security manager, and OTA-capable firmware structure are all resident on-module, exposing a simple UART API or BGSCRIPT environment to the host. Typical applications include battery-powered IoT sensors, fitness and health accessories, smart tags and beacons, and industrial wireless sensor nodes - anywhere a certified Bluetooth Smart link must be added without RF expertise. The integrated chip antenna keeps the BOM minimal and removes antenna tuning from the design cycle. A key design consideration: the BLE113-A-V1 variant contains only 128 kB of flash. If you plan over-the-air firmware updates or a large BGSCRIPT application, the pin-compatible BLE113-A-M256K with 256 kB flash is the better choice within the same footprint. This page synthesizes distributor pricing, drop-in alternatives, practical design notes, and migration guidance from Silicon Labs application note AN1036 - information not consolidated in the manufacturer datasheet alone.
BLE113-A-V1C - Bluetooth 4.0 Smart Module, 2V-3.6V | Silicon Labs
The Silicon Labs BLE113-A-V1C is a Bluetooth Smart (Bluetooth v4.0 low energy) Class 2 module targeted at small, low-power sensors and accessories, operating from a 2V to 3.6V supply with 2Mbps over-the-air data rate on a 36-pin SMD land pattern with an integrated chip antenna. A Bluetooth Smart module is a complete wireless subsystem that integrates the 2.4GHz Bluetooth radio, a microcontroller, the BLE software stack, and GATT-based profiles into a single certified unit. Within the system hierarchy, it sits between a discrete BLE chipset design (radio IC plus external host MCU plus software) and a full system-on-chip; modules such as the BLE113 fall into the broader categories of RF module, transceiver module, and wireless connectivity IC. Key features include full integration of radio, MCU (8051-based, running the Bluegiga Bluetooth Smart stack), and antenna, which removes RF layout effort and regulatory certification burden. Supply operation from 2V to 3.6V allows direct powering from a 3V coin cell. The module can host end-user applications via BGScript or the BGAPI serial protocol, meaning many designs need no external microcontroller at all - a significant saving in size, BOM cost, and power. Architecturally, the BLE113 combines a Bluetooth radio with an integrated MCU executing the Bluetooth low energy protocol stack and GATT profiles. The V1C variant carries the standard flash configuration of the BLE113 family (128kB flash; the A-M256K variant offers 256kB for OTA updates and larger BGScript applications). Typical applications include battery-powered sensor nodes, proximity and iBeacon-style beacons, wearable accessories, smart-home devices, and small medical/health peripherals where compact size and low average current dominate. Design consideration: because the V1C uses an internal chip antenna, keep clearance around the antenna area per the Bluegiga layout guidelines; the A-V1 variant (external antenna connection) is the choice when metal or enclosure constraints demand an external antenna.

BLED112-V1 - Bluetooth 4.0 BLE USB Dongle | Silicon Labs
The Silicon Labs BLED112-V1 is a single-mode Bluetooth Low Energy (Bluetooth 4.0) USB dongle operating in the 2.402 GHz to 2.48 GHz ISM band at 1 Mbps, with -91 dBm receiver sensitivity and approximately 30 m range, housed in a USB Type-A dongle form factor powered from a 3.6 V to 5.5 V USB supply. A BLE USB dongle is a complete wireless connectivity module that integrates the Bluetooth radio, a microcontroller running the BLE protocol stack, and an antenna into a USB stick. In the connectivity hierarchy it sits at the module level: Bluetooth 4.0 single-mode device (BLE only), implemented as a network co-processor controlled by an external host over USB. Unlike standard Bluetooth dongles that rely on the operating system Bluetooth stack, the BLED112 exposes the full BLE controller and GAP/GATT functionality to the application. Key features include full BLE 4.0 single-mode operation, the Bluegiga BGAPI serial protocol that lets any external host (PC, MCU, LabVIEW) control the stack over USB, the BGScript scripting language for standalone operation, and the Bluegiga Profile Toolkit for rapid custom GATT profile prototyping. The integrated antenna removes RF design effort, and -91 dBm sensitivity supports robust links up to roughly 30 m in line-of-sight conditions. Architecturally, the BLED112 embeds Silicon Labs (Bluegiga) BLE silicon with on-board flash running the Bluetooth stack, so the host only needs to send BGAPI commands over the USB CDC interface. This bypasses the limitations of native Windows, macOS, and Linux BLE stacks, giving applications full control over GATT communication and BLE advertisements - a key reason it is widely used in test fixtures and instrumentation. Typical applications include adding BLE connectivity to PCs and embedded hosts for sensor data acquisition, BLE development and profiling with two dongles, LabVIEW-based BLE test systems, and robotics and IoT gateway links. Design consideration: because the part is end-of-life, plan a migration path early; the BGAPI protocol is shared across the Silicon Labs BLE module family, which eases firmware-level porting even though a mechanical USB-dongle drop-in is scarce. This page synthesizes distributor availability data, BGAPI ecosystem information, drop-in replacement analysis, and practical design notes not found together in the manufacturer datasheet.
BLED112-V1C - Bluetooth 4.0 Low Energy USB Dongle | Silicon Labs
The Silicon Labs BLED112-V1C is a Bluetooth v4.0 Low Energy (BLE) USB dongle transceiver module operating in the 2.402 GHz to 2.48 GHz band with integrated antenna, -91 dBm receiver sensitivity, and up to 30 m range, powered from a 3.6 V to 5.5 V supply over USB. A BLE dongle is a finished, fully certified Bluetooth Low Energy radio unit in a USB stick form factor. Unlike bare RF modules that require antenna design and regulatory testing, a dongle integrates the radio, microcontroller, BLE stack, and antenna, and plugs directly into a host USB port. In the connectivity hierarchy it sits under: Bluetooth module -> short-range wireless transceiver -> RF transceiver finished unit -> wireless communication device. Key features include Bluetooth v4.0 single-mode low energy operation at 1 Mbps, a UART serial interface alongside native USB, support for the Bluegiga BGAPI binary protocol and BGScript scripting, and R&TTE Directive (1999/5/EC) conformity with Anatel certification (06875-18-03402) for Brazil. These attributes allow hosts without native BLE to gain BLE connectivity with zero RF design effort. Architecturally, the BLED112 combines an integrated Bluetooth radio, microcontroller, and pre-flashed software stack. Application logic can run on-board using the Bluegiga Profile Toolkit and BGScript, or the host can drive the module over BGAPI, offloading the entire BLE stack from the host CPU. This makes it a favorite in PC-based instrumentation and test setups. Typical applications include adding BLE to lab equipment and data loggers, Linux, Android, and Windows host connectivity for BLE sensors, BLE profile prototyping using two dongles, and industrial wireless configuration tools. The 30 m range and integrated trace antenna suit desktop and benchtop use. Design consideration: because the dongle is a finished USB unit, the main integration risk is host driver and BGAPI software compatibility rather than RF layout; plan software migration early since the family is nearing end-of-life.

BLUENRG-M0A - BLE v4.2 Module, -85dBm, 2.4GHz | STMicroelectronics
The STMicroelectronics BLUENRG-M0A is a very low-power Bluetooth Low Energy (BLE) v4.2 network processor module built around the BlueNRG-MS SoC, housed in an integrated surface-mount chip antenna package. The module operates across the 2.4 GHz to 2.4835 GHz ISM band and delivers up to +8 dBm transmit power with -85 dBm receiver sensitivity, providing robust link margins for typical IoT indoor and outdoor deployments. It supports Bluetooth SIG end-product certification with pre-certifications across major world regions, dramatically reducing time-to-market for connected products. A Bluetooth Low Energy (BLE) module is a self-contained radio subsystem that integrates the transceiver IC, crystal, antenna, and matching network into a single surface-mount unit, allowing designers to add wireless connectivity without RF layout expertise. Within the connectivity hierarchy, BLE sits below Wi-Fi in data rate (typically 1 Mbps) but offers much lower power consumption (peak currents in the single-digit milliamp range), making it the preferred choice for coin-cell and energy-harvesting IoT devices. The BLE module category itself bridges wireless transceiver ICs and complete wireless modules. Key specifications include 20 mA peak transmit current, ultra-low sleep current, SPI host interface (up to 8 MHz), and an integrated 32 MHz crystal. The module supports master and slave roles simultaneously and operates from -40 °C to +85 °C. According to the BlueNRG-M0 modules flyer, the BLUENRG-M0A is pin-compatible with the BLUENRG-M0L ceramic antenna variant, enabling designers to migrate between antenna types on the same PCB footprint. The BlueNRG-MS die inside the module uses a Cortex-M0 core architecture with embedded Bluetooth protocol stack, offloading all link-layer and host-stack processing from the external host MCU. This network-processor approach minimizes host-side firmware complexity while preserving full BLE v4.2 feature coverage, including LE Privacy 1.2, LE Data Length Extension, and up to eight simultaneous connections. Typical applications include wearable fitness bands, BLE beacons (iBeacon and Eddystone), industrial sensor nodes, smart home bridges, medical monitoring patches, and remote control units. The combination of pre-certified module-level compliance and ultra-low power makes it particularly suitable for battery-powered products targeting FCC, CE, IC, TELEC, and KCC regulatory domains. When designing with the BLUENRG-M0A, route the host SPI bus with short traces and 50 Ω-controlled impedance where possible, and place at least 5 mm of clearance around the chip antenna area to avoid ground-plane detuning. Decoupling VDDL with a 100 nF ceramic capacitor placed within 3 mm of the pin ensures stable operation across load transients. This page synthesizes distributor pricing, drop-in compatible alternatives across the BlueNRG module family, and practical RF design notes not found in the standalone datasheet - including a parameter-by-parameter comparison against the M0L, M2SA, and M2SP variants.
BLUENRG-M0L - Bluetooth v4.2 LE Module 2.4GHz | STMicroelectronics
The STMicroelectronics BLUENRG-M0L is a Bluetooth v4.2 compliant, very low-power network processor module that operates in the 2.4 GHz to 2.4835 GHz ISM band. It is a surface-mount integrated chip antenna module that combines an embedded Bluetooth low-energy protocol stack with master/slave role support and simultaneous multiple-role operation, enabling concurrent sensor and hub functions on the same module. A Bluetooth Low Energy (BLE) module is a certified sub-system that bundles the radio transceiver, baseband, protocol firmware, and often an integrated antenna into a single reflow-solderable package. Within the wireless connectivity hierarchy, BLE modules sit below bare SoCs and above discrete 2.4 GHz radios: they trade flexibility for faster time-to-market because the wireless regulatory certification and stack integration are already completed by the module vendor. The BlueNRG-M0 family targets ultra-low-power IoT nodes where battery life, footprint and BOM count matter more than raw compute. Key features include Bluetooth v4.2 master/slave support, multi-role operation, an integrated chip antenna, surface-mount packaging in an 11-SMD module form factor, and an output power of 6 dBm. The BLUENRG-M0L variant differs from the BLUENRG-M0 in its regulatory certifications and is built around the BlueNRG-MS silicon. Sensitivity is rated at -85 dBm, receive current is 16.36 mA, and transmit current is 13.25 mA to 27.35 mA depending on output power setting. Architecturally, the BLUENRG-M0L is built around a low-power Cortex-M0 core running ST's embedded Bluetooth low-energy stack. The integrated chip antenna, RF matching network, crystals, and passive components are pre-tuned inside the module, so the host MCU only communicates with it over a UART/SPI host interface. This removes the need for 50-ohm RF layout expertise and saves several weeks of PCB iteration. Typical applications include BLE sensor nodes, beacons, smart-home hubs, fitness and medical wearables, industrial telemetry, and remote controls. The -40C to +85C operating range makes it usable in outdoor and industrial deployments. Because the regulatory certification is pre-done, designers can skip the FCC/CE/IC RF certification cycle and ship products faster. When designing with the BLUENRG-M0L, leave the antenna keep-out area clear of copper on all PCB layers and avoid placing metal components or shields above the antenna. Provide a stable 1.7 V to 3.6 V supply and place a 1 uF decoupling capacitor close to the module's VDD pin. The host MCU must drive the module via the documented ACI (Application Command Interface) over SPI or UART; firmware updates go through the bootloader. This page synthesizes distributor pricing, package-level drop-in variants, and practical design notes for fast time-to-market BLE designs that go beyond what the ST datasheet flyer alone provides.

The module supports industrial operating temperature range of -40C to +85C. A Bluetooth Low Energy (BLE) module is a type of short-range RF module that integrates a Bluetooth radio, baseband controller, and protocol stack into a single shielded unit. Within the wireless hierarchy, it sits between discrete RF transceiver chips and fully qualified end products, allowing OEMs to skip costly Bluetooth SIG qualification and RF tuning. BLE, also called Bluetooth Smart, is the low-power variant of the Bluetooth 802.15.1 standard optimized for battery-powered devices. Key features of the BM71 family include Bluetooth 5.0 compliance delivering up to 2.5x throughput improvement over Bluetooth 4.1 based designs, more secure connections, an on-board chip antenna requiring no external RF matching, and full shielding for coexistence with other radios. The embedded firmware implements the complete BLE stack, so the host MCU only needs a simple UART interface. Technically, the BM71 uses Microchip's certified radio with an embedded protocol stack, offloading advertising, connection management, GATT services, and security pairing from the host processor. Configuration is performed via simple ASCII or transparent UART commands, reducing firmware complexity and certification burden. Typical applications include IoT sensor nodes, smart home devices, battery-powered beacons, industrial wireless sensors, and connected medical accessories, where the module's low power sleep modes and small 9 x 11.5 mm footprint fit space- and energy-constrained designs. Design consideration: keep the module antenna region clear of ground planes and metal per Microchip's layout guidelines, and power the module from a clean 3.3V rail with local decoupling. This page synthesizes distributor availability, same-family drop-in alternatives, and practical design notes not found in the manufacturer datasheet.
BM71BLES1FC2-0B02AA - BLE 5.0 Module 9x11.5mm | Microchip
The Microchip Technology BM71BLES1FC2-0B02AA is a fully certified Bluetooth 5.0 Low Energy (BLE) transceiver module operating in the 2.4 GHz ISM band, housed in a shielded 9 x 11.5 x 2.1 mm surface-mount package with an integrated chip antenna and -90 dBm receiver sensitivity. A Bluetooth Low Energy module is a complete wireless subsystem that integrates a BLE radio, baseband, protocol stack, and antenna into a single certified unit. In the system hierarchy it sits above discrete RF ICs (which require external stack development and RF design) and below complete host systems, functioning as a serial-to-BLE bridge that frees the host MCU from managing the Bluetooth software stack, timing-critical RF firmware, and regulatory certification. Key features of the BM71BLES1FC2-0B02AA include Bluetooth Core 5.0 compliance with up to 2.5x throughput improvement over earlier BM70-generation silicon, a completely integrated Bluetooth software stack with configuration via simple ASCII commands over UART, a shielded enclosure for EMI reduction, and an integrated chip antenna on a regulatory-certified variant. Supply voltage spans 1.9 V to 3.6 V, suiting single-cell lithium and 3.3 V logic designs, and the module is rated for industrial temperature environments. Architecturally, the BM71 embeds Microchip's BLE silicon with flash memory for stack and application script storage. The certified, shielded, antenna-integrated construction means the RF matching network, crystal, and antenna have been tuned by Microchip, removing the most error-prone portion of a wireless design. Developers interact with the module as a wireline replacement: UART data in, BLE data out. Typical applications include smart-home sensors and actuators, battery-powered IoT beacons, industrial wireless configuration and diagnostic links, and connected health accessories. The industrial temperature rating and shielded package also suit networked lighting controls and commercial building automation. A key design consideration is layout: although the antenna is integrated, keep at least the datasheet-recommended keep-out area free of copper and plastics above the antenna region to preserve the certified radiation pattern and sensitivity. This page synthesizes distributor pricing (as of 2026-10-19), drop-in family alternatives, design notes, and long-tail selection guidance not found in the manufacturer datasheet.
BM83SM1-00AB Bluetooth 5.0 Stereo Audio Module | Microchip
The Microchip Technology BM83SM1-00AB is a Bluetooth 5.0 stereo-audio transceiver module operating from 2.402 GHz to 2.48 GHz in a PCB-trace, surface-mount package. It supports Bluetooth Classic BR/EDR and Bluetooth Low Energy, together with HFP 1.7, HSP 1.2, A2DP 1.3, SPP 1.2, AVRCP 1.6, PBAP 1.2, GATT, and GAP. The module can receive audio through Auxiliary Input or I2S and stream it to as many as two paired Bluetooth sink devices using Audio Transceiver firmware. A Bluetooth audio module combines a short-range radio, baseband protocol stack, audio interface, and embedded control functions in one surface-mount assembly. The BM83 belongs to the RF transceiver-module hierarchy rather than a discrete Bluetooth IC: designers connect the module to a host product through power, control, communication, and audio interfaces instead of implementing an RF antenna network and Bluetooth firmware from scratch. Its Class 1 designation identifies it as a Bluetooth audio module intended for conventional short-range wireless audio links. The BM83SM1-00Tx configuration provides A2DP source capability, allowing legacy audio equipment to become a Bluetooth transmitter. A2DP Source and Sink support supports product designs that transmit or receive stereo audio. HSP 1.2 supports legacy headset roles, while HFP 1.7, PBAP 1.2, AVRCP 1.6, and SPP 1.2 address hands-free calling, phone-book access, media control, and serial data services. AAC and SBC decoding further broadens compatibility with common Bluetooth audio sources. The module integrates the radio and protocol functions required for embedded Bluetooth connectivity, reducing RF-layout exposure at the product level. Nevertheless, an embedded module does not eliminate antenna-design requirements: the PCB, copper, enclosure, ground distribution, and matching network still determine practical RF performance. Firmware selection and host-interface integration are equally important because protocol support alone does not establish the final user experience. Typical uses include Bluetooth audio dongles, wireless speakers, headphones, soundbars, automotive-accessory adapters, home-audio upgrades, and dual-sink speaker systems. Auxiliary Input suits products with an existing analog source, while I2S supports digital audio integration. The stated ability to stream to two paired sink devices is particularly useful when one product must share audio with two headphones or speakers. For implementation, follow the manufacturer datasheet for the exact 50-lead land pattern, exposed-pad or thermal requirements, supply sequencing, UART or control behavior, firmware configuration, and antenna clearance. Preserve the documented keep-out regions around the module and connect its RF reference and ground features exactly as specified. Do not assume that another BM83 suffix is interchangeable without checking revision, antenna, firmware, and regulatory differences.
BM83SM1-00TA Bluetooth 5.0 Stereo Audio Module | Microchip
The Microchip Technology BM83SM1-00TA is a Bluetooth 5.0 stereo audio module operating across 2.402 GHz to 2.48 GHz in a 50-lead surface-mount package. It combines Bluetooth Classic BR/EDR and Bluetooth Low Energy connectivity with integrated audio-transceiver firmware. According to the verified Microchip product material, the module supports HFP 1.7, HSP 1.2, A2DP 1.3, SPP 1.2, AVRCP 1.6, and PBAP 1.2, including A2DP source and sink operation. A Bluetooth audio module is a wireless connectivity and embedded-control subsystem that adds Bluetooth communication to an audio product without requiring a discrete radio design. In the broader product hierarchy, this module is a Bluetooth transceiver module, an RF and wireless module, and an embedded audio bridge. It can receive audio through auxiliary input or I2S and stream that audio to up to two paired Bluetooth sink devices, making it useful for dongle-style designs and products without native Bluetooth. The BM83SM1-00TA is qualified for Bluetooth 5.0 and supports Classic BR/EDR as well as BLE. Its profile set covers hands-free, headset, advanced audio distribution, serial port, audio/video remote control, and phone-book access functions. A2DP source and sink capability supports both sending audio to headphones or speakers and receiving audio from a paired source. The module also supports AAC and SBC decoding, broad protocol support, and GATT/GAP services. The BM83 family is intended for stereo-audio connectivity in compact embedded products. Its integrated module approach reduces the need to design and qualify a separate RF radio, antenna structure, audio interface, and Bluetooth protocol stack on the host PCB. Firmware configuration remains important: the BM83SM1-00Tx variant implements A2DP source capability using Audio Transceiver firmware, so host firmware and command sequences must match the intended audio role. Typical uses include Bluetooth audio dongles, wireless speakers, headphones, source accessories, home-audio adapters, and embedded audio gateways. The verified data confirms the frequency range, Bluetooth version, protocol profiles, audio inputs, and dual-sink streaming behavior. Electrical limits, pin names, supply voltage, antenna requirements, and package dimensions should be taken from the manufacturer datasheet before PCB release. PCB implementation must preserve the module’s required antenna clearance, ground connectivity, audio routing, and power decoupling. Keep RF-sensitive and audio-sensitive traces away from noisy switching paths where practical, provide the manufacturer-specified bypass capacitors close to the supply pins, and follow the reference layout for antenna and exposed grounding. Validate RF performance with the intended enclosure because plastic, cables, grounding, and nearby structures can change the installed antenna behavior. This product-data page combines the verified Microchip feature description, distributor identification, and cross-reference search results. It distinguishes confirmed facts from missing electrical details and avoids inventing a pinout or package drawing that was not present in the supplied sources. For production use, compare the selected BM83SM1 variant, firmware image, regulatory requirements, and supplier availability before committing the design.
BMD-341-A-R - BLE 5.0/Thread/Zigbee Module | u-blox
The u-blox BMD-341-A-R is a stand-alone Bluetooth 5.0 Low Energy, Thread, and Zigbee (IEEE 802.15.4) multiprotocol transceiver module operating in the 2.4 GHz band, based on the Nordic Semiconductor nRF52840 SoC with an ARM Cortex-M4F CPU, supplied in a 10.2 x 15.2 mm surface-mount package with a U.FL connector for an external antenna (antenna not included). A Bluetooth Low Energy (BLE) module is a short-range radio subsystem that integrates the radio, modem, processor, crystal, and RF matching network into a certified, pre-tested unit. Modules sit above raw SoCs in the wireless hierarchy, reducing RF design effort, certification cost, and time to market for connected products. Key features include full Bluetooth 5.0 long-range support, 802.15.4 Thread and Zigbee protocols, and an open CPU architecture that lets developers run their own firmware on the embedded nRF52840 with 1 MB flash and 256 KB RAM. The U.FL connector enables optimized external antennas for maximum range.

BP35A1 - 920MHz Wi-SUN Module with 32-bit MCU | ROHM
The ROHM BP35A1 is a 920MHz specified low-power radio module certified for the Wi-SUN (Wireless Smart Utility Network) standard, integrating a 32-bit microcontroller, Wi-SUN B-route firmware, and a built-in antenna in a connector-joint-type package. Receiver sensitivity is -103dBm typical at 100kbps with BER below 0.1%, providing high communication quality for smart-meter and home-energy-management links. A Wi-SUN module is a radio-frequency transceiver module that implements the Wi-SUN mesh networking protocol stack, a wireless standard used widely in utility infrastructure such as smart electricity, gas, and water meters. Within the system hierarchy, the BP35A1 sits at the module level: it combines a sub-GHz RF transceiver, baseband, protocol firmware, and host microcontroller into a single certified unit, so designers do not need to develop RF circuitry or obtain radio certifications themselves. Key features include operation in the 920MHz band, integrated Wi-SUN B-route profile firmware, a built-in antenna that removes external antenna matching from the design, and a connector joint type interface that allows the module to be plugged into a host PCB rather than soldered, simplifying assembly and field replacement. The -103dBm sensitivity at 100kbps (BER < 0.1%) supports long-range, low-data-rate mesh links typical of HAN (Home Area Network) single-hop topologies. The module is Wi-SUN Alliance certified as product WSA0064 (HEMS Controller, HAN single-hop). Technically, the BP35A1 integrates the RF transceiver, a 32-bit microcontroller running the Wi-SUN stack, and regulatory-certified radio parameters in one module, per the ROHM featured-products documentation. This integration reduces RF design risk, eliminates RF layout iteration, and shortens time to certification for ECHONET-Lite-based smart meter systems. Typical applications include smart electric meter HAN communication (B-route), home energy management system (HEMS) controllers, building energy monitoring, and sub-GHz mesh sensor networks in the 920MHz band. A key design consideration: because the module uses a connector joint type interface, plan the host-side mating connector and keep-out zone early; ROHM offers the dedicated BP35A7A 2.54mm-pitch conversion adapter board for evaluation and prototyping. This page synthesizes distributor availability, drop-in alternative analysis, and practical design guidance not found in the manufacturer datasheet.
BP35C5 - Wi-SUN FAN Sub-GHz Transceiver Module | ROHM
The ROHM BP35C5 is a Wi-SUN FAN compatible Sub-GHz wireless communication module operating in the 902 MHz to 928 MHz band, with 13.8 dBm output power, -105 dBm receiver sensitivity, and a supply voltage range of 2.6 V to 3.6 V, housed in a surface-mount module package with convex long-side terminals (1206-metric footprint classification, BP35C5-1 package). A Wi-SUN (Wireless Smart Utility Network) module is a radio transceiver with an integrated 32-bit MCU that implements the Wi-SUN FAN (Field Area Network) mesh networking protocol, an international standard optimized for smart community and utility infrastructure. Wi-SUN FAN devices form self-healing mesh networks supporting frequency-hopping spread spectrum, making them a power-management-layer building block for large-scale IoT deployments such as smart meters and street lighting. Key features of the BP35C5 include a maximum data rate of 300 kbps, receiver sensitivity of -105 dBm for extended link budget, and UART and GPIO host interfaces that simplify integration into existing systems. The module is certified under both Wi-SUN and FCC (US) regulations, significantly reducing end-product certification effort and enabling immediate evaluation. Technically, the BP35C5 integrates a Sub-GHz RF transceiver and 32-bit microcontroller running the Wi-SUN FAN stack, exposing a command-based UART interface so host processors do not need to implement the mesh protocol themselves. This offloads protocol complexity, flash footprint, and RF layout challenges from the host design. Typical applications include smart electricity, gas, and water metering networks, street lighting control, and smart city infrastructure across North America (902-928 MHz ISM band). Design consideration: an antenna is not included; ensure a 50-ohm matched antenna connection and verify FCC modular-approval conditions for the final enclosure.

BR-100AH-US - 802.11ah Wi-Fi HaLow Ethernet Bridge | Silex
The Silex Technology BR-100AH-US is a 10/100 Ethernet-to-802.11ah (Wi-Fi HaLow) wireless bridge operating in the sub-1 GHz band at 926.5 MHz (US SKU), delivering over 1 Mbps throughput in a standalone boxed enclosure with one RJ-45 Fast Ethernet port. An Ethernet-to-wireless bridge is a networking device that connects any Ethernet-equipped equipment to a wireless network by transparently converting wired frames to radio frames. In the network hierarchy it sits at the edge of the wireless LAN as a wireless client (station) with an embedded wired switch port, allowing legacy devices without native Wi-Fi to join a WLAN without driver or application changes. Key features include support for IEEE 802.11ah, the long-range, low-power Wi-Fi HaLow standard that operates below 1 GHz for dramatically better wall penetration and range than 2.4 GHz or 5 GHz Wi-Fi; software-transparent operation requiring no changes to drivers, management tools, or applications; multi-client mode operation; and a simple 10/100 Ethernet interface that makes integration plug-and-play. The 802.11ah radio in the 920-928 MHz unlicensed band trades raw bandwidth for range and link robustness, making it well suited for machine-type traffic at megabit-class data rates. Because the BR-100AH-US presents itself as a standard network device, industrial controllers, printers, cameras, and medical instruments can be relocated anywhere in a facility with wireless coverage. Typical applications include factory automation and industrial IoT sensor networks, smart building and metering infrastructure, and medical device connectivity where long range and wall penetration matter more than gigabit speeds. Design consideration: place the bridge within verified HaLow access point coverage and confirm regional regulatory fit - the US SKU (926.5 MHz) must not be deployed in regions using different 802.11ah channel plans such as China or Europe. This page synthesizes distributor availability, regulatory SKU information, and practical deployment notes not consolidated in the manufacturer datasheet.

The -1XL-Y variant adds a 25 Gigabit Ethernet uplink option to the proven Supervisor-1XL platform, providing investment protection as enterprises migrate from 10G aggregation to 25G core links. It is built around the Cisco UADP 2.0 ASIC with a programmable pipeline, microengine capabilities, and template-based allocation of Layer 2/3, forwarding, QoS, and ACL resources, ready for next-generation enterprise and SD-Access services including MPLS, VRF-aware Locator/ID Separation Protocol, and host-tracking database features. The supervisor occupies the dedicated supervisor slot in the Catalyst 9404R, 9407R, and 9410R chassis (one active plus one redundant SSO supervisor), and ships with 240 GB of SSD storage by default for IOS XE image, packages, and telemetry buffers. Two SFP28 uplink ports provide the 25G migration path while QSFP ports (numbered 9 and 10 on this -1XL-Y SKU) support 40G operations via QSFP transceivers with LC, copper, or MPO-12 connectors. A supervisor engine in a modular access/aggregation chassis is the centralized control plane and switching fabric manager: it runs the routing protocol stack, manages the line-card forwarding ASICs, terminates management access, and houses the bootflash, DRAM, and SSD that host Cisco IOS XE. Within Cisco's modular hierarchy, the C9400-SUP-1XL-Y sits between the entry-level C9400-SUP-1 (80 Gbps/slot, 1/10/40G uplinks) and the flagship C9400X-SUP-2/2XL (480 Gbps/slot, 100G uplinks, UADP 3.0sec), offering a balanced 240 Gbps/slot middle ground for buyers who need 25G uplinks today but do not yet require 100G or UADP 3.0sec scale. Key features include 240 Gbps per-slot switching capacity, dual SFP28 25G uplinks, dual QSFP 40G uplink ports (ports 9-10), SSD-backed storage, Stateful Switchover (SSO) for hitless failover, advanced routing (MPLS, BGP, OSPF, EIGRP, IS-IS), SD-Access border node capability, and full IOS XE programmability via Guest Shell, Python, and NETCONF/YANG APIs. The C9400-SUP-1XL-Y uses the UADP 2.0 ASIC combined with a multi-core x86 CPU complex and hardware-accelerated cryptography. Compared with the original C9400-SUP-1, the -1XL variant triples per-slot bandwidth from 80 Gbps to 240 Gbps, enabling full 10G line-card oversubscription-free operation and paving the way for mGig/25G access tiers. Typical applications include enterprise core switching for campus and branch aggregation, MPLS-aware SD-Access border or collapsed-core nodes, 25G server-farm aggregation in mid-sized data centers, and high-availability dual-supervisor deployments in the Catalyst 9404R, 9407R, and 9410R modular chassis. When designing around the C9400-SUP-1XL-Y, plan for two supervisor slots per chassis, populate redundant SSO supervisor pairs for hitless failover, and pair the supervisor with line cards that do not require the higher-bandwidth C9400X-SUP-2/2XL (some newer C9400 line cards are restricted to the X-series supervisors only, so verify compatibility per the line card matrix). This page aggregates verified distributor specifications, drop-in supervisor alternatives in the same Catalyst 9400 family, and practical design notes not consolidated in the Cisco datasheet.
