• The default switch pin is A2
  • The default NeoPixel pin is A3

NeoPixel Jumper

  • A3 - This jumper is located on the back of the board, below the NeoPixel LED, and is labeled A3. If you cut this jumper, it disconnects the NeoPixel data input pin from pin A3 and you can then connect the NeoPixel to another available pin by soldering a wire.

NeoPixel Pad

  • Neo - This solder pad is located at the bottom of the board, to the right of the BFF NeoKey silk text and the NeoPixel Jumper. It is labeled Neo. This pad is attached to the NeoPixel data input pin and can be used to wire the NeoPixel to a different pin if the NeoPixel jumper is cut to disconnect it from pin A3.

MX Key Jumper

  • A2 - This jumper is located on the back of the board, next to the key socket and is labeled A2. If you cut this jumper, it disconnects the switch output from pin A2 and you can then connect the NeoPixel to another available pin by soldering a wire.

MX Key Pad

  • Sw - This solder pad is located at the bottom of the board between the Sw silk text and BFF NeoKey silk text. It is labeled Sw. This pad is attached to the key output pin and can be used to wire the key to a different pin if the MX key jumper is cut to disconnect it from pin A2.
