Using the input and output interface, several modules can be daisy chained together. A single module can drive a 8*8 common cathode dot matrix.

Product Introduction:

1.Single module can drive a 8*8 common cathod dot matrix

2.Operating Voltage:5V

3.Size:3.23.21.3cm

4.With 4 pcs fixing screw holes,diameter 3mm

5.With input and output interface,support several modules cascading

Includes 4 pcs fixing screw holes, diameter 3mm

Instructions

Left side of module is Input, right side is Output.

When controlling a single module you only need to connect the input port with CPU

When daisy chaining several modules, connect the first modules input with CPU, the conncet the output port with the second module's input port; the second module's output port connects with the third module's input port and so on

Take 51 MCU as example: VCC-5V; GND-GND; DIN-P2.2; CS-P2.1; CLK-P2.0
