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.
As another option you can buy it from these locations not affiliated with this project. They are given to help you locate premade boards but no guarantees are given or implied:

- Seller #2 (fill me)
-
The Passive-RPi1 adapter board is to connect one panel to Raspberry Pi 1 with 26 GPIO pins.
