The Badger'd nRFNANO is an Arduino ProMicro form factor nrf52840 development board.

nRFNANO comes with fully compatible pinout with nice!nano. In addition to that you will have an exposed pad to add extra safety for your charging circuit which allows you to connect a temperature sensor.

It comes with UF2 drag and drop bootloader which makes life way much easier for developers. With extra isolated PCB antenna, it will provide relatively powerful signal which allows more stable connections when there are obstacles in between.
