BMD-345 Module for Bluetooth 5 and 802.15.4
The BMD-345 is an advanced, highly flexible, ultra-low power multiprotocol SoM that enables Bluetooth 5 (BLE) and
IEEE 802.15.4 (Thread and Zigbee) connectivity for portable, extremely low power embedded systems. With an ARM®
Cortex™-M4F CPU, integrated 2.4GHz transceiver, and an integrated antenna, the BMD-345 provides a complete RF
solution allowing faster time to market with reduced development costs. Providing full use of the Nordic nRF52840’s
capabilities and peripherals, the BMD-345 can power the most demanding applications, all while simplifying designs
and reducing BOM costs. The BMD-345 is an ideal solution for designs that require the latest Bluetooth 5 features or
802.15.4 based networking for Thread. Increased integration with built in USB and 5.5V compatible DC/DC supply
reduces design complexity and BOM cost, while expanding possible applications. BMD-345 designs are footprint
compatible with the BMD-301, providing low-cost flexibility for tiered product lineups.
