Nice!Nano

by Nice Keyboards

Image of Board

The nice!nano is a Pro Micro replacement development board offering BLE using the nRF52840 chip. It has the same pinout as the Pro Micro meaning it will work with almost any Pro Micro keyboard. The nice!nano also has a 3.7 V lithium battery charger on board as well as a software level switch to cut off power to LEDs, which can eat 1 mA each even when off.

Technical details

  • Mid mount USB-C port making the board a 3.2 mm total thickness (thinner than a Pro Micro)
  • nRF52840 chip on board with 1 MB of Flash and 256 KB of RAM
  • Adafruit Bootloader loaded offering DFU flashing as well as flashing via UF2 storage
  • 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
  • 5 extra GPIO pins (3 thru holes and 2 pads on the back) offering a total of 23 GPIO pins
  • 3.3 V out of the VCC pin to power external features
  • 32.768 kHz oscillator on board for real-time clock capabilities

CircuitPython 7.3.0-rc.0

This is the latest unstable release of CircuitPython that will work with the Nice!Nano.

Unstable builds have the latest features but are more likely to have critical bugs.

Absolute Newest

Every time we commit new code to CircuitPython we automatically build binaries for each board and language. The binaries are stored on Amazon S3, organized by board, and then by language. Try them if you want the absolute latest and are feeling daring or want to see if a problem has been fixed.

Past Releases

All previous releases are listed on GitHub, with release notes, and are available for download from Amazon S3. They are handy for testing, but otherwise we recommend using the latest stable release. Some older GitHub release pages include the same binaries for downloading. But we have discontinued including binaries as assets on newer release pages because of the large number of files for each release.

Update UF2 Bootloader

Latest version: 0.6.3

The bootloader allows you to load CircuitPython, MakeCode, and Arduino programs. The bootloader is not CircuitPython. You can check the current version of your bootloader by looking in the INFO_UF2.TXT file when the BOOT drive is visible (FEATHERBOOT, CPLAYBOOT, etc.).

It is not necessary to update your bootloader if it is working fine. Read the release notes on GitHub to see what has been changed. In general, we recommend you not update the bootloader unless you know there is a problem with it or a support person has asked you to try updating it.

Updating the bootloader on nRF52840 boards is an involved process right now. Follow the instructions in this README.

After you update, check INFO_UF2.TXT to verify that the bootloader version has been updated. Then you will need to reload CircuitPython.
