Jumper E8

Add a fair amount of solder to bridge the E and 8 jumper pads on the back of the RGB matrix bonnet.

This is necessary for the RGB matrix bonnet to work with the 64x64 RGB matrices.

Jumper Wire for RGB Matrix Bonnet

Make a short wire to bridge two GPIO pins on the RGB Matrix Bonnet.

The wire in the photo is about 3in(76mm) in length.

Solder Jumper Wire

Connect the jumper wire to GPIO #4 and GPIO #18 on the RGB Matrix Bonnet.

The LIS3DH accelerometer is optional and only needed for the “sand” program. If you only plan on running the globe and Game of Life programs, this part can be omitted and you can skip the next few steps.

STEMMA Cable for LIS3DH

A STEMMA QT cable will make it easier to connect to the LIS3DH breakout board.

Prep STEMMA Cable

Cut off the male header pins and use wire strippers to expose the tips of each wire.

Tin the wires by adding a bit of solder. This will prevent the strands of wire from fraying.

Solder Cable to RGB Matrix Bonnet

Connect the wires from the STEMMA QT cable to the following pins on the RGB Matrix Bonnet.

  • Red wire to VCC
  • Black wire to GND
  • Blue wire to SDA
  • Yellow wire to SCL

Connect LIS3DH to RGB Matrix Bonnet

Double check the wires from the STEMMA QT cable have been correctly soldered to the pins on the RGB Matrix Bonnet.

Plug in the STEMMA QT cable to the side of the LIS3DH with the on LED.
