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 boosts the link budget even further, bringing range and coverage to the maximum. Built-in USB and 5.5 V compatible DC-DC supply reduce design complexity and BOM cost, while expanding possible applications. The modules are certified for Europe, US, Canada, and Australia/New Zealand.
