Use the DFRobot 64×64 RGB matrix panel with a Raspberry Pi 3 B+ to bring a dance party with you wherever you go!
DFRobot reached out to me to do a sponsored project for their 64×64 RGB
LED matrix. At first I had tried to use it with the ESP32 Firebeetle, but I couldn’t get the library to work. So that meant using a Raspberry Pi 3 B+.Adafruit also has a guide that you can follow here: https://learn.adafruit.com/adafruit-rgb-matrix-pl…
Thankfully Adafruit has a matrix HAT for the Raspberry Pi that handles all of the 3.3v -> 5v logic level conversions.
Both the HAT and matrix have the same connector, but pin 8 (the white
wire) doesn’t get plugged into the HAT. Because the HAT only supports up to 4 control wires, pin 8, which is the 5th control wire, gets connected to GPIO pin 24.
