Buy MAX7219 Dot Matrix Module Microcontroller LED Module Display Module MAX7219 DIY Kit


Description:

· A single module can drive an 8*8 common negative lattice
· Module operating voltage: 5V
· Module size: 3.2 cm long, 3.2 cm wide and 1.5 cm high
· With 4 fixed screw holes and 3 mm diameter, it can be fixed with M3 copper column.
· Modules with input and output interfaces support multiple modules cascade

Wiring instructions:

The left side of the module is the input port, and the right side is the output port.
When controlling a single module, you only need to connect the input port to the CPU.
When multiple modules are cascaded, the input end of the first module connects to the CPU, the output end connects to the input end of the second module, the output end of the second module connects to the input end of the third module, and so on.
Take 51 single chip computer as an example:
· VCC 5V
· GND GND
· DIN_P20
· CS_P21
· CLK_P22

Package included:

1 x MAX7219 Dot Matrix Module DIY kit
