Surface Mount Bluetooth v5.0, Thread, Zigbee Transceiver Module (2.4GHz, U.FL)

The BMD-34 series are advanced, highly flexible, ultralow-power multiprotocol modules that enable concurrent Bluetooth® 5, Thread and Zigbee (IEEE 802.15.4) connectivity for portable, extremely low power embedded systems, offering the greatest radio range and coverage. With an Arm® Cortex®‑M4 with FPU, integrated 2.4 GHz transceiver, an extended range of interfaces and embedded hardware cryptographic engine, the BMD-34 modules provide a complete RF solution allowing faster time to market with reduced development costs and advanced security capabilities. Providing full use of the Nordic nRF52840’s capabilities and peripherals, the BMD-34 can power the most demanding applications, all while simplifying designs and reducing BOM costs.

The BMD-34 is an ideal solution for designs that require Bluetooth 5 features or 802.15.4 based networking for Thread and Zigbee. The Bluetooth 5 long range feature provides extended range, and the optional PA/LNA boost the link budget even further, bringing range and coverage to the maximum. Built in USB and 5.5 V compatible DC-DC supply reduces design complexity and BOM cost, while expanding possible applications. The modules are certified for Europe, US, Canada, and Australia/New Zealand.

Surface Mount Bluetooth v5.0, Thread, Zigbee Transceiver Module (2.4GHz, U.FL) Product Help and Resources

Core Skill: Soldering

This skill defines how difficult the soldering is on a particular product. It might be a couple simple solder joints, or require special reflow tools.

4 Soldering

Skill Level: Experienced - You might be required to do some reflow or basic rework with SMD components. A heat gun, Heaterizer or other tools might be required, and a good understanding of SMD soldering as well as PTH soldering are required.
See all skill levels

Core Skill: Programming

If a board needs code or communicates somehow, you're going to need to know how to program or interface with it. The programming skill is all about communication and code.

3 Programming

Skill Level: Competent - The toolchain for programming is a bit more complex and will examples may not be explicitly provided for you. You will be required to have a fundamental knowledge of programming and be required to provide your own code. You may need to modify existing libraries or code to work with your specific hardware. Sensor and hardware interfaces will be SPI or I2C.

Core Skill: Electrical Prototyping

If it requires power, you need to know how much, what all the pins do, and how to hook it up. You may need to reference datasheets, schematics, and know the ins and outs of electronics.

3 Electrical Prototyping

Skill Level: Competent - You will be required to reference a datasheet or schematic to know how to use a component. Your knowledge of a datasheet will only require basic features like power requirements, pinouts, or communications type. Also, you may need a power supply that?s greater than 12V or more than 1A worth of current.
