MAX7219 Dot Led Matrix Module MCU LED Display Control Module Kit For Arduino

Description:
Module operating voltage: 5V
A single module can drive an 8 * 8 common cathode lattice
With four screws hole, aperture 3mm, by using our M3 Tongzhu fixed.
Module with input and output interfaces, supports multiple modules cascade.

Wiring instructions:
1.The module left as an input port to the output port on the right.
2.The control of a single module, simply input port to the CPU.
Multiple modules cascade input termination CPU, 2 output termination module, a module of the input of the input terminal, the output terminal of the first two modules of the first three modules, and so on ... 51 MCU, for example:

VCC → 5V
GND → GND
DIN → P22
CS → P21
CLK → P20
