MAX7219 Dot LED Matrix Module

The MAX7219 Dot LED Matrix Module is a compact and easy-to-use display module designed for showing numbers, characters, symbols, and scrolling text. It integrates the MAX7219 LED driver IC, which handles multiplexing and current control internally—reducing wiring and microcontroller load.

This module communicates using the SPI protocol, making it fully compatible with Arduino, ESP32, ESP8266, Raspberry Pi, and other microcontrollers. Multiple modules can be daisy-chained together to create larger displays, ideal for message boards and digital signboards.
