Product Description

Brighten your projects with the MAX7219 Single 8x8 Dot LED Matrix Module. This compact display unit features 64 high-intensity red LEDs arranged in an 8x8 grid, all driven by the industry-standard MAX7219 serial input/output common-cathode driver IC. At Robogears, we recommend this module for its simplicity and efficiency; it allows you to control a full 64-LED matrix using only three data pins from your microcontroller. Designed for seamless integration, the module includes pre-soldered input and output headers, making it easy to create custom scrolling text displays or symbolic indicators for your Arduino or ESP8266 projects.

Detailed Key Features

  • Efficient Serial Interface: Employs a 3-wire serial SPI interface (DIN, CS, CLK), minimizing the I/O footprint on your microcontroller while maintaining high-speed updates.

  • Integrated Multiplexing: The onboard MAX7219 IC handles all LED multiplexing and BCD decoding internally, ensuring a flicker-free display and reducing software overhead.

  • Expandable Layout: Features output headers that allow you to "daisy-chain" multiple 8x8 modules together to create larger display surfaces or longer scrolling banners.

  • Software-Controlled Brightness: Supports 16 levels of digital brightness control via code, allowing you to optimize visibility for different lighting conditions.

  • Robust Mounting Design: The PCB includes four 3mm mounting holes, ensuring secure attachment to your project chassis or 3D-printed enclosures.

All Technical Details

  • Pin Configuration: VCC, GND, DIN (Data In), CS (Chip Select), CLK (Clock).

  • Cascading Pins: DOUT (Data Out), CS, CLK pins available for linking the next module in the series.

  • Compatibility: Fully compatible with 5V logic levels; for 3.3V controllers (like ESP32), a logic level shifter is recommended for long-term stability.

  • LED Driver Type: Common Cathode configuration.

  • Refresh Rate: High-speed internal scan frequency ensures smooth animations and text scrolling.

Prototyping & Engineering Tips (Robogears Exclusive)

  • Power Management: A single 8x8 matrix can draw up to 150mA when all LEDs are on at full brightness. If you are linking four or more modules at your Pimpri workshop, ensure your 5V power supply can handle the cumulative current, as the Arduino's 5V pin may overheat.

  • Wiring Protocol: When daisy-chaining, the DOUT of the first module must connect to the DIN of the second. The CLK and CS pins should be connected in parallel across all modules.

  • Library Tip: Use the LedControl or MD_MAX72xx libraries for Arduino. They provide simple commands to display characters, shapes, and custom animations with just a few lines of code.

  • Common Ground: Always ensure that the GND of your external power supply is shared with the GND of your microcontroller to maintain signal integrity and prevent data corruption.

Package Includes

  • 1 x MAX7219 Single 8x8 Dot LED Matrix Module
