LED Matrix Module.max7219

1.Module Size: length 3.2cm X width 3.2cm X height 1.3cm
2.The module has an input and output interface, supporting multiple modules cascade.
3. With 4 fixing screw holes, the hole diameter is 3mm.
4. A single module can drive an 8*8 common cathode lattice
5. Module Working Voltage: 5V

Wiring Instructions:
1. The left side of the module is the input port, and the right side is the output port.
2. When controlling a single module, you only need to connect the input port to the CPU.
3. When multiple modules are cascaded, the input terminal of the first module is connected to the CPU, the output terminal is connected to the input terminal of the second module, the output terminal of the second module is connected to the input terminal of the third module, and so on
