_Use the DFRobot 6464 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 6464 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._
