Módulo de Control de matriz de puntos MAX7219, controlador de Control de microcontrolador, KIT DIY, módulo LED MCU, módulo de pantalla

Module parameters:
- single module can drive a 8*8 common cathode lattice

- module working voltage: 5V
- module size: length 3.2 cm X 3.2 cm wide and 1.5 cm high X
, with 4 fixed screw holes with diameter of 3mm and M3 can be used in fixed pillars
- module with input and output interface, support multiple modules cascade
Connection description:
The left side of the module is the input port, and the right is the output port.
When controlling a single module, the input port is only required to be connected to the CPU
Cascading multiple modules, the first module input end is connected with the CPU and input end of the input end of the output end is connected to the second module, output terminal of the second module connected with the three modules, and so on.
