Rigado's Bluetooth 5 (BLE) and Thread (IEEE 802.15.4) modular solution, the BMD-340 is an advanced, highly flexible, ultra-low power multiprotocol SoM for portable, extremely low power embedded systems. With an ARM® Cortex™-M4F CPU, integrated 2.4GHz transceiver, and an integrated antenna, the BMD-340 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-340 can power the most demanding applications, all while simplifying designs and reducing BOM costs. The BMD-340 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-340 designs are footprint compatible with the BMD-300/301, providing low-cost flexibility for tiered product lineups.
