This module is made up of 4 matrices each of 8 by 8 LEDs. Each 8 x 8 matrix has its own MAX7219 driver, creating an 8 x 32 LED dot matrix display. The Arduino communicates using serial data, needing just 3 I/O to drive the whole display.

Features:

  1. The left side of the module to the input port, the right to an output port
  2. When the control of a single module, simply input port connected to CPU
  3. When a plurality of cascaded modules, input and output termination CPU, an input terminal of the second output end of the first module a module, the first two modules of the input terminal of the three termination modules, and so on...
  4. 51 microcontrollers, for example:
  5. VCC 5V
  6. GND GND
  7. DIN P2.2
  8. CS P2.1
  9. CLK P2.0
  10. Size for manual measurement, there may be a 0 to 2 cm error, belongs to the normal phenomenon.
  11. And due to the difference between different monitors, the picture may not reflect the actual color of the item.

Specifications

  1. Operating Voltage: 5V
  2. A single module can drive a 8x8 dot matrix common cathode
  3. Dimensions: 12.8X12.8X1.3 cm
  4. Fixing screws with 64 holes with a diameter 3mm
  5. Module with input and output interfaces, support for cascading multiple modules

Package Include:

  1. 1x MAX7219 Dot Matrix Module 4-in-1
  2. 1x 20cm DuPont line 5pin

I need an example code please, to interface this display with my Arduino Mega 2560. I want to display readings in realtime.
