Cylewet MAX7219 Dot Matrix Module 4 in 1 Display for Arduino Microcontroller with 5Pin Line CYT1045
64 fixed screw holes with 3mm in its diameter
A single module can drive a 8x 8 dot matrix common cathode
Dimension of Module: 12.8X 12.8X 1.3cm
Operating voltage: 5V
Equipped with input and output interfaces, support for multiple modules to cascade
Instruction of Wiring: The left side of the module to the input port, the right to the output port When control a single module, simply connect the input port to CPU When multiple modules are cascaded, input port of the first module connects to CPU, its output port to the input port of the second module, and the output port of the second module to the input port of the third module, and so on. Take 51 microcontrollers for example: VCC→ 5V GND→ GND DIN→ P2.2 CS→ P2.1 CLK→ P2.0
