Display module MAX7219 dot matrix module control module MCU module
1. A single module can drive an 8×8 common yin lattice
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, 3 mm aperture, can be fixed by our M3 copper column
5. Module with input and output interface, supporting multiple module cascade
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. ..
