LED Matrix 8x8 5.5V MAX7219 Cascadable For Arduino
This LED matrix module is a versatile display unit that allows users to create dynamic visual content with ease. It is ideal for scrolling text, symbols, and graphical representations in embedded and Arduino-based projects.
Package Includes:
- 1 x 8x8 Matrix Red LEDs
- 1 x Driver Board
- 1 x Connecting Cable
Specifications:
- Drive Capability: Supports 8 x 8 common cathode LED matrix (64 individually addressable LEDs)
- Operating Voltage: 5V
- Dimensions: 5 x 3.2 x 1.5 cm (L × W × H)
- LED Color: Red
- Mounting: Four mounting holes (3mm diameter)
- Cascading Support: Can cascade multiple modules via input/output headers
Wiring Instructions:
- The left side of the module contains the input port; the right side has the output port.
- To control a single module, connect the MCU to the input port.
- To use multiple modules, connect the output of one module to the input of the next.
Arduino Uno Wiring:
- VCC → 5V
- GND → GND
- DIN → Pin 12
- CS → Pin 10
- CLK → Pin 11

Creating Graphics:
You can create your own custom graphics and characters using the “PixelToMatrix” software tool. Simply draw your pattern and convert it to a byte array automatically.
Example: Creating the character “O”:
Arduino Code:
The Arduino code for driving the LED matrix is available for download. Make sure to install the required library.
Libraries:
- LedControl Library – GitHub
- Install by placing the unzipped folder into your Arduino
librariesdirectory
