Description

MAX7219 Dot Matrix 4 In 1 8×8 Display 5P Line Module For Arduino

Feature:

A single module can drive a 8×8 dot matric common cathode
Operating voltage: 5V
Dimension: 12.8 x 12.8 x 1.3cm
Fixing screws with 64 holes with a diameter 3mm
Module with input and output interfaces,support for cascading multiple modules

How to use:

The left side of the module is the input port, the right is an output port
When the control of a single module, simply input port connected to CPU
When you want to control several modules, just the input port of the first module connect to the CPU, then the output port connect to the input port of the second module, the output port of the second module connect to the input port of the third module, and so on…

Take 51 Microcontrollers as an example:

VCC → 5V
GND → GND
DIN → P2.2
CS → P2.1
CLK → P2.0

Package includes:

1 x MAX7219 4 in 1 module
