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](./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](./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](./passive-rpi1) adapter board is to connect one panel to
Raspberry Pi 1 with 26 GPIO pins.
