Four 8x8 Matrices in One Module with Daisy-Chaining and Easy SPI Control
This MAX7219 4-in-1 Dot Matrix LED module combines four individual 8×8 LED matrices into a single 32×8 visual display, driven by a single MAX7219 driver chip. It’s designed for DIY electronics, Arduino projects, IoT dashboards and embedded display solutions that require dynamic text, icons, graphics or scrolling animations with minimal pin usage.
Key Features:
4-in-1 LED matrix: 256 LEDs across four addressed matrices.
MAX7219 driver IC: uses a 3-wire SPI interface (DIN, CS, CLK) for efficient control.
Operating Voltage: 5 V DC, compatible with Arduino and most microcontroller boards.
Cascading Support: easily connect multiple modules to expand your display area.
Adjustable brightness: programmatically control LED intensity for different environments.
5-pin connector included: simplifies wiring and installation.
Typical Applications:
✔️ Scrolling text and message boards – real-time display of information.
✔️ Digital clocks, counters and timers.
✔️ Status dashboards for sensors and IoT systems.
✔️ Game displays and interactive projects.
✔️ Educational kits and maker builds – learn how to interface displays with microcontrollers.
Why Choose This Module:
The MAX7219 driver reduces wiring complexity by handling LED multiplexing and brightness control internally. With libraries like LedControl and MD_MAX72XX, you can implement text scrolling, animations, and visual effects easily even as you cascade multiple displays.
A single module can drive a 8x8 dot matrix common cathode
Working voltage: 5V
Module size: 132 x 33 x 17 mm
With 64 fixing screw holes, hole diameter: 3mm
Module with input and output interfaces, support for cascading multiple modules
Wiring:
1. The left side of the module is the input port, and the right is the output port.
2. Control of a single module, the input port only need to receive CPU.
3. The more a module cascade and input end of the first module is connected with the CPU and input end of the input end of the output end is connected to the second module, output terminal of the second module connected with the three modules, and so on.
For example: 51
VCC→5V
GND→GND
DIN→P2.2
CS →P2.1
CLK→P2.0
