PCB adapter for Raspberry Pi to Hub75 RGB Matrixes

Since hand-wiring can be a little tedious, here are some PCBs that help with the wiring when using the rpi-rgb-led-matrix code.

  • Passive-3 Supports three parallel chains, directly connected to the output of a Rapsberry Pi with 40 GPIO pins. Works, but usually it is better to buffer the outputs using the ...
  • Active-3 board. Supports three parallel chains with active buffering and 3.3V -> 5V level shifting for best reliability. Requires SMD soldering.
  • The Passive-RPi1 adapter board is to connect one panel to Raspberry Pi 1 with 26 GPIO pins.
