MAX7219 8×8 Dot Matrix MCU

Module parameters:

1. A single module can drive an 8*8 common negative dot matrix

2. Module working voltage: 5V

3. Module size: length 5 cm X width 3.2 cm X height 1.5 cm

4. With 4 fixing screw holes, the hole diameter is 3mm, can be fixed by our M3 copper column

5. Module with input and output interface, support multiple modules cascade

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.
