The nice!nano is a Pro Micro drop-in replacement board that makes building wireless keyboards a breeze.
Built using power-conscious design and parts, the nice!nano stretches battery life to its limits.
With a mid-mount USB-C port, the nice!nano is only 3.2mm thick. That's thinner than a Pro Micro!
The recommended Lipo battery for use with the nice!nano controller is the 351230 3.7v 120mAh (Australia shipping only)
The v2 updates:
- Reduced quiescent (system idle) power by ~70%
Increased through hole pad sizes to make soldering easier
Reduced battery pin size to avoid incorrect installation
Charge boost added to optionally increase charge rate from ~100mA to ~500mA
- Miscellaneous changes to reduce GPIO failures, improve thermals, and reduce component failures
- Mid mount USB-C port making the board a 3.2mm total thickness (thinner than a Pro Micro)
- nRF52840 chip on board with 1MB of Flash and 256KB of RAM
- Adafruit Bootloader loaded offering DFU flashing as well as flashing via UF2 storage (similar to dragging a file to a flash drive!)
- Programmable indicator (blue) LED as well as a charging indicator (orange) LED
- Battery voltage reader to report battery percentage to main device
- External power can be cut off using an on board MOSFET saving power from LEDs (each can draw 1mA when off!)
- 5 extra GPIO pins (3 thru holes and 2 pads on the back) offering a total of 23 GPIO pins
- 3.3V out of the VCC pin to power external features
- 32.768 kHz oscillator on board for real-time clock capabilities
- Clean design with matte black solder mask, immersion gold plating, and Tg 170 FR4 for durability

Work as advertised. However, I got confused on this product because I bought the Contra 40% Keyboard Kit. Which said that it worked with QMK. However, even though this board was recommend for purchased with the keyboard kit, it only runs ZMK. If you want QMK you have to go with a different board. This was my first keyboard I built from a kit. However, I feel like it shouldn't be recommended on a kit that advertised that it will work with QMK.
