To satisfy electronic DIY hobbyists, we had developed this MAX7219 Dot Matrix Module. It uses the Max7219 chip which do a great job on saving of MCU I/O. It can not only control each point individually, but also can be extended without limitation to meet your requirements on LED Sign, Team Logo and so on.
Since the master chip is used in Max7219 to- make product have the following characteristics:
1).The transmission efficiency of up to 10MHz.
2).Can be individually controlled for each point.
3).Lowest power consumption of 450uA (one module).
4).Power-on reset automatically display full black
5).Serial communication, a great saving of MCU IO, also can be extended To expand the program with SPI.
6).For each screen brightness control, by setting the Max7219 instructions.
