RGB-Matrix-Px-80x40

The RGB-Matrix-P4-80x40 is an 80×40 full-color LED dot matrix display featuring 3,200 RGB LEDs with a 4mm pixel pitch. It supports platforms such as Raspberry Pi, Pi Pico, ESP32, and Arduino, and comes with open-source example code and tutorials.

Precautions

Note
  • Before connecting the display, it is recommended to measure the terminal output voltage as shown in the diagram below.
  • If the measured voltage is -5V, the terminal polarity may be abnormal. Please contact customer service to replace the corresponding terminal.
  • The display operates at 5V and requires an external 5V power supply. Do not connect any other voltage to avoid damaging the device.
