Hi there! The nice!nano is a drop-in replacement for
the Pro Micro that offers wireless connectivity via
Bluetooth. I’ve been developing this for the past five
months, and it’s almost ready for a group buy! Please fill
out the IC form to let me know what your preferences for the
group buy would be along with other details like
firmware.

The nice!nano is thinner, more powerful, and most
importantly has wireless Bluetooth abilities built in.
Here’s a list of the features:
- Mid mount USB-C port making the board a 3.2mm total thickness (thinner than a Pro Micro)
- Extra exposed pins to add a rechargeable lithium battery
- Works over USB as well
- 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!)
- On board lithium battery charger through the USB C port (100mA charge rate)
- Extremely low power making the board capable of lasting a few weeks on a 100mAh battery
- 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
I’m super excited to get these in people’s hands! Let me know what you think.
