Hardware for Pi
Use the following hardware for the Pi 4
- 4x M3 x 10mm FF standoffs
- 8x M3 x 6mm screws
Install Standoffs to Pi
Insert the M3 screws through the top of the Pi mounting holes and secure the standoffs to the bottom of the PCB.
Proceed to install standoffs on all four mounting holes.
Test Pi Mount on Panel
Take a moment to test fitting the Pi mount by placing it over the brackets on Panel #5.
Check the magnets to ensure the polarity matches in order to correctly attach to to the panel.
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 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.
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.
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.
