The nice!nano is a microcontroller board with Bluetooth and USB, pin-compatible with a 3.3V Pro Micro. It uses the nRF52840 microcontroller from Nordic Semiconductor.
- Mid-mounted USB Type C port, making it slimmer than a Pro Micro.
- On-board Lithium battery charger (100 mA max).
- Charging LED
- Voltage out can be switched off in software.
- Real-time clock
- Three additional GPIO pins compared to the Pro Micro, plus two GPIO pads.
Support for the nRF52840 chip are in:
- BlueMicro firmware
