Press Release: u-blox acquired Rigado’s Bluetooth modules business and extends Bluetooth Low Energy offerings for customers 

BMD-341: Bluetooth 5 + 802.15.4 + U.FL

Status: Pre-release
Evaluation Kits Coming Soon

Rigado’s Bluetooth 5 (BLE), Zigbee and Thread (IEEE 802.15.4) modular solution, the BMD-341 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 a U.FL connector for an external antenna, the BMD-341 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-341 can power the most demanding applications, all while simplifying designs and reducing BOM costs. The BMD-341 is an ideal solution for designs that require the latest Bluetooth 5 features, Zigbee 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-341 designs are footprint compatible with the BMD-300/301/330, providing low-cost flexibility for tiered product lineups.
