Product description
The BMD-345-EVAL kit provides stand-alone use of the BMD-345 module featuring the Nordic
nRF52840 RF System on Chip (SoC) and a Skyworks RFX2411 Power Amplifier / Low Noise Amplifier
(PA / LNA).
The evaluation kit provides a great starting point for almost any Bluetooth 5 low energy, Thread, or
Zigbee project. All features of the BMD-345 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, user LEDs, and a reset button. 44 GPIO are available
on headers that are compatible with the Arduino® form factor. This allows easy use of 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-345-EVAL board.
