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 64×64 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

Soldier the lower pins of the jumper to drive 64×64 panels. This applies to the panels linked above.
