The nice!nano is a wireless, BLE enabled replacement for the Pro Micro powered by the nRF52840 SoC.

Includes square post headers to install the device, but it is recommended to socket the controllers.

Requires a 3.7v lithium rechargeable battery. The 301230 lithium battery is a good fit.

For more information including build tips, firmware, and more, read the documentation. Please note that these controllers require different firmware than the Pro Micro and Elite-C controllers. Be sure to read the documentation for more information about compatibility.


  • 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 (picture coming soon)
