Description

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, only need to connect the input port to the CPU. 3.When multiple modules are cascaded, the input of the first module is connected to the CPU, the output is connected to the input of the second module, the output of the second module is connected to the input of the third module, and so on... Take 51 microcontroller as an example: VCC → 5V GND → GND DIN → P2.2 CS → P2.1 CLK → P2.0 Only 3 IO ports are needed to drive 1 dot matrix!No flashing when dot matrix display! Support cascading!
