Dot matrix 8x8 display with max7219 led module for arduino
Description:
1 single module can drive an 8x8 dot matrix common cathode
2 operating voltage module: 5v
3 dimensions 12.8 cm x 3.2cm wide x 1.3 cm high length module
4 holes with screws 3mm diameter
5 modules with input and output interfaces, support for cascading multiple modules.
