Introduction
The BMD-34x-EVAL kit from Rigado allows for stand-alone use of the BMD-340, BMD-341, BMD-370, or
BMD-380 module featuring the Nordic nRF52840 RF System on Chip (SoC). Other Rigado modules have
evaluation kits covered by other documents.
The Evaluation Kit provides a great starting point for almost any Bluetooth 5 Low Energy, Thread, or
Zigbee project. All features of the BMD-340/341/370/380 are easily accessed from the evaluation
board. A simple USB connection provides power, programming, and a virtual COM port. Four user
buttons are available, as well as a USB peripheral connector, four LEDs and a reset button. All 48 GPIO
are available on headers that are compatible with the Arduino form factor (44 GPIO for the BMD-380).
This allows easy use of any existing Arduino shields. Current sense resistors allow for measuring
current into the module and into the shield.
This guide provides setup instructions for starting development and describes the hardware
functionality of the BMD-34x-EVAL boards.
