1 Functional description

The BMD-380 is a small form factor, advanced, highly flexible, ultra-low power multiprotocol System

on Module (SoM) that enables Bluetooth 5 low energy and IEEE 802.15.4 (Thread and Zigbee)

connectivity for portable, extremely low power embedded systems. With an Arm® Cortex®-M4 with

FPU processor, integrated 2.4 GHz transceiver, and an integrated antenna, the BMD-380 provides a

complete RF solution allowing faster time to market with reduced development costs. Providing full

use of the Nordic Semiconductor nRF52840’s capabilities and peripherals, the BMD-380 can power

the most demanding applications, all while simplifying designs and reducing BOM costs. The BMD-

380 is an ideal solution for designs that require Bluetooth 5 features or 802.15.4 based networking

for Thread and Zigbee. Increased integration with built in USB and 5.5 V compatible DC/DC supply

reduces design complexity and BOM cost, while expanding possible applications.
