The board detailed description and schematic is available here.

Flash the board

The board is flashed using the adafruit-nrfutil Python package:

$ pip install --user adafruit-nrfutil

Example with hello-world application:

make BOARD=adafruit-clue -C examples/hello-world flash

Accessing STDIO via UART

The STDIO is directly accessible via the USB port. On a Linux host, it's generally mapped to /dev/ttyACM0.

Use the term target to connect to the board serial port

make BOARD=adafruit-clue -C examples/hello-world term

The TERM_DELAY environment variable can be used to add a delay (in second) before opening the serial terminal. The default value is 2s which should be enough in most of the situations.
