MAX7219-4 Dot Matrix LED Display Module – 4-in-1 Cascaded Panel

This Dot Matrix LED Module incorporates the powerful MAX7219 driver chip, making it incredibly easy to add eye-catching animations and dynamic displays to your electronic projects.

Each individual module contains an 8×8 LED matrix (64 LEDs), with all LEDs precisely controlled via the MAX7219 for custom visual patterns. The main advantage? You get full control over all 64 LEDs using just three communication lines from a microcontroller such as an Arduino, Raspberry Pi, or any other compatible MCU.

This version of the product features four 8×8 dot matrix modules pre-cascaded into a single compact display, offering an extended area for text, graphics, and animations — perfect for scrolling messages or dashboards.

Easy Expandability

Need a bigger display? No problem. You can daisy-chain additional modules effortlessly by connecting the output pins of one module to the input pins of the next. Create extended displays by simply plugging them in — the MAX7219 handles the rest.

Key Features:

• Plug-and-play with most microcontrollers (Arduino, STM32, ESP32, etc.)

• Requires only 3 digital I/O pins (DIN, CLK, CS) to control the entire module

• Cascadable design — easily chain multiple modules together

• Bright, clear LED display with low power consumption

• Compact size with M3 mounting holes on the PCB

• Individual LED control with no need for constant refreshing
