Instruction for P3 LED matrix connect ESP32 module

  • Scan number: 32
  • Pitch: 3mm
  • Size: 7.56 in x 7.56 in(192mm x 192mm)
  • Signal socket: HUB75
  • Drive ic: universal double buff
  • Line code: 3-8 decode
  • Power input: DC 5V
  • Brightness: max 1200 CD
  • power consumption: max 12W

I designed the kit for ESP32 linking LED matrix HUB75, or you need manually connect ESP32 to hub75e.
