Max7219 Dot Matrix Module Control Module Microcontroller Module Display Module Wire Feeding

Module parameters:

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

2. Module operating voltage: 5V

3. Module size: Length 5cm X Width 3.2cm X Height 1.5cm

4. Equipped with 4 fixed screw holes with a diameter of 3mm, which can be fixed using our M3 copper pillar

5. The module comes with input/output interfaces and supports cascading multiple modules

Wiring instructions:

1. The left side of the module is the input port, and the right side is the output port.

When controlling a single module, simply connect the input port to the CPU

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 ..
