MAX7219 Dot Matrix Display Panel 32X8

MAX7219 Dot Matrix Display Panel 32X8 P3.75 is used with a microcontroller and Arduino or any controlling unit for showing data and string.

Specifications:

A single module can drive an 8×8 dot matrix common cathode
Working voltage: 5V
Module size: 12.8 x 3.2 x 1.3 cm (L*W*H)
With 64 fixing screw holes, hole diameter: 3mm
Module with input and output interfaces, support for cascading multiple modules

Wiring:

1. The left side of the module is the input port, and the right is the output port.
2. Control of a single module, the input port only needs to receive CPU.
3. The more a module cascade and input end of the first module is connected with the CPU and input end of the input end of the output end is connected to the second module, the output terminal of the second module is connected with the three modules, and so on.
