Assembly.
- Download and burn the PI image with the custo software (link)
- Mount the 6 panels in a structure using the hex screws and the 3D printed parts.
- If using 64x64 LED panels, the bonnet must first be modified to properly drive this configuration by soldiering a jumper on the back (see figure below).
- Connect the bonnet to the PI and connect all the cables
