Module parameters:
1. A single module can drive an 8*8 common cathode dot matrix
2. Module operating voltage: 5V
3. Module size: 5 cm long x 3.2 cm wide x 1.5 cm high
4. With 4 fixing screw holes, the hole diameter is 3mm, and can be fixed with our store's M3 copper column
5. The module has input and output interfaces and supports multiple module cascades
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 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 → P22
CS → P21
CLK → P20
Delivery list:
1. One MAX7219 dot matrix module (finished product, with dot matrix, tested)
2. 5 DuPont wires
