1Pcs Microcontroller Module Arduino 4 In One Display MAX7219 Dot Matrix Module

1. A single module can drive a 8x8 dot matrix common cathode.    2. Operating voltage: 5V.    3. dimensions: length 12.8 cm X 12.8 cm wide and 1.3 cm high X.    4. fixing screws with 64 holes with a diameter 3mm.    5. module with input and output interfaces, support for cascading multiple modules.    Wiring instructions.    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.    51 microcontrollers, for example.    VCC → 5V.    GND → GND.    DIN → P2.2.    CS → P2.1.    CLK → P2.0.
