MAX7219 Dot Matrix Module 4-in-1 Red Display (MAX7219 Dot Matrix Display)
Description:

Looking for easy to control LED matrix? This 4 in 1 Dot Matrix Display module should be suitable for you. The whole module comes in four 8x8 RED common cathode dot matrix that equiped with MAX7219 IC each. Great to display running text and picture. It can be cascaded to bigger dot Matrix display, but do make sure the current of 5V is sufficient to support it.

Specifications:

A single module can drive a 8x8 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 need 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, output terminal of the second module connected with the three modules, and so on.
For example: 51 SCM
VCC→5V
GND→GND
DIN→P2.2
CS →P2.1
CLK→P2.0

Package includes:

1 x MAX7219 Dot Matrix Module
1 x 5pin jumper Cable
