The Single MAX7219 Dot Matrix Display Module RED Color (8×8 LED Dot Matrix Display) is a high-performance LED display module designed for visual output in microcontroller and embedded system projects. Powered by the MAX7219 display driver IC, this module provides full control over 64 individual LEDs using only a few microcontroller pins, making it ideal for Arduino, ESP8266, ESP32, Raspberry Pi, PIC, AVR, STM32, and other development boards.

The MAX7219 driver includes a BCD code-B decoder, multiplexing circuitry, digit/segment drivers, and built-in 8×8 static RAM that stores display data. This allows individual LEDs or rows/columns to be updated without refreshing the entire display. With adjustable brightness control and daisy-chaining capability, this module is perfect for scrolling text displays, animations, counters, timers, status indicators, graphics, and creative LED projects.

It requires only one external resistor to set LED current, making it simple, efficient, and reliable. The module is pre-soldered and includes a red LED dot matrix display, providing bright and clear visibility for indoor or semi-outdoor applications.
