Product description
The BMD-34-EVAL kits provide stand-alone use of the BMD-340 or BMD-341 module
featuring the Nordic nRF52840 RF System on Chip (SoC). Other 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 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. 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-34-EVAL boards.
