MAX7219 Dot Matrix Module For Arduino Microcontroller 4 In One Display with 5P Line

Product Description
Wiring Instructions:
Operating Voltage: 5V
A single module can drive a 8×8 dot matrix common cathode
Operating Voltage: 5V
Dimensions: 12.8X12.8X1.3cm/
Fixing screws with 64 holes with a diameter 3mm
Module with input and output interfaces, support for cascading multiple modules
Quality: 1Set
The left side of the module to the input port, the right to an output port
When the control of a single module, simply input port connected to CPU
When a plurality of cascaded modules, input and output termination CPU, an input terminal of the second output end of the first module a module, the first two modules of the input terminal of the three termination modules, and so on…
51 microcontrollers, for example:
DIN P2.2
CS P2.1
CLK P2.0
Size for manual measurement, there may be a 0 to 2 cm error, belongs to the normal phenomenon.
And due to the difference between different monitors, the picture may not reflect the actual color of the item.

Note: A single module can drive a 8×8 dot matrix common cathode
