nRF52 board

This one is supported:
https://wiki.makerdiary.com/nrf52840-mdk/
https://docs.zephyrproject.org/latest/boards/arm/nrf52840_mdk/doc/index.html


I have this one:
https://wiki.makerdiary.com/nrf52840-mdk-usb-dongle/

LEDs are the same on both

P0.22 green
P0.23 red
P0.24 blue

So that should be fine.

Trying it out:

cd /nix/exo/zephyr-project/zephyr
. ~/.zephyrrc
export PYTHONPATH=/home/tom/.local/lib/python3.7/site-packages
west build -p auto -b nrf52840_mdk samples/basic/blinky
