MAX7219 Dot Matrix Module for Arduino Microcontroller 4 in 1 Display with 5pin Line

Description

Operating Voltage: 5V
A single module can drive a 8x8 dot matrix common cathode
Dimensions: 12.8X12.8X1.3 cm
Fixing screws with 64 holes with a diameter 3mm

Wiring instructions:
- 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:
VCC 5V
GND GND
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.
