MAX7219 Dot Matrix Module Microcontroller 4 In One Display with 5P Line Module parameters: 1. A single module can drive an 8*8 negative lattice 2. Module working voltage: 5V 3. Module size: 12.8cm long X 3.2cm wide X 1.3cm high 4. With 64 fixed screw holes and aperture of 3mm 5. Modules with input and output interfaces support multiple modules cascading 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 cascade, the input end of the first module is connected to CPU, the output end is connected to the input end of the second module, the output end of the second module is connected to the input end of the third module, and so on... Take 51 MCU as an example: The VCC - 5 v GND to GND DIN - P2.2 CS - P2.1 The CLK - P2.0 Package Include:MAX7219 dot matrix module is four in one And 5P Line
