Aokin MAX7219 Dot Matrix Module 4 in 1 Display? for Arduino Microcontroller with 5Pin Line

Product description Wiring Instructions: A single module can drive a 8x8 dot matrix common cathode Operating Voltage: 5V Fixing screws with 64 holes with a diameter 3mm 1, Module with input and output interfaces, support for cascading multiple modules 2, The left side of the module to the input port, the right to an output port 3, When the control of a single module, simply input port connected to CPU 4, 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...

Take 51 MCU for example: VCC ? 5V GND ? GND DIN ? P2.2 CS ? P2.1 CLK ? P2.0

Specification: Dimension of Module: 129 * 32 * 12mm/5.09 * 1.26 * 0.47inch LED Color: Green. Left Side: Input Port Right Side: Output Port It is designed to be broken into smaller segments or additional units could be purchased and chained together. Set state to true to false to turn an LED on or off respectively. Great for your Arduino projects.

Size for manual measurement, there may be a 0 to 2 cm error, belongs to the normal phenomenon. And due to the difference between different monitors, the picture may not reflect the actual color of the item. Thank you!

Package Includes: 1x MAX7219 Dot Matrix Module 4-in-1 1x 20cm DuPont line 5pin
