Pi Mount Prep

The 3D printed Pi mount uses 4x magnets to attach to panel #5.

Get the magnets and panel #5 ready for installation.

 

Test Fit Mount

The Pi mount attaches to the flat tabs on panel #5.

Place the Pi mount over the panel and use the magnets to determine the correct polarity needed for installing.

Install 4x magnets onto the tabs of the Pi mount.

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 a couple of steps until you get to the Raspberry Pi mounting instructions further down.

Hardware for LIS3DH 

M2.5 hardware is used to secure the LIS3DH accelerometer to the Pi mount.

Place the LIS3DH over the Pi mount and line up the mounting holes.

Double check the orientation and placement is the same as the photo.

TEMPORARY NOTE: PLEASE SCREAM AT THEM TO GET THE ACCELEROMETER ORIENTATION RIGHT. If it’s flipped 180°, sand won’t work right and they’ll have to tear it down and rearrange this part.

Secure LIS3DH to Pi Mount

Use the following hardware to secure the LIS3DH accelerometer to the Pi mount.

  • 4x M2.5 x 10mm screws
  • 4x M2.5 hex nuts

Install Standoffs to Raspberry Pi

Secure 4x M2.5 x 10mm long standoffs with 4x M2.5 x 6mm long screws.

 

Install RGB Matrix Bonnet

Install the RGB Matrix bonnet onto the GPIO headers of the Raspberry Pi.

Get the Pi ready to secure to the 3D printed mount.

Secured Pi

Place the Pi 4 over the mount and line up the mounting holes.

Reference the photo for correct placement.

Install and fasten 4x M2.5 x 6mm long screws to secure the Pi to the mount.

Cables for Pi 

Get the following cables ready to connect to the Raspberry Pi.

  • 1x USB type A to USB-C short cable
  • 1x USB type A to 2.1mm DC jack cable
  • 2x Wires for RGB Matrix Bonnet

Install Power Wires to RGB Matrix Bonnet

Insert the two wires into the screw block terminals on the RGB Matrix Bonnet. Red wire to voltage, black wire to ground.

Use a screw driver with flat head bit to secure the wires to the screw block terminals.

Connect Cables to Pi

Plug in the USB-C cable to the USB-C connector on the Raspberry Pi.

Plug in the 2.1mm DC jack cable to the DC jack on the RGB Matrix Bonnet.
