8 X 8 Product parameters:
A single module can drive an 8 * 8 common cathode lattice
Working voltage: 5V
Size: 3.2 (length) * 3.2 (width) * 1.3 (height) cm
With 4 screw holes, aperture 3mm
With input output interface, supporting cascading of multiple modules
Available in three colors: red, blue, and green
Attention: When welding the dot matrix and base plate, there may be some unevenness and skewness. If you mind, do not buy.
Instructions for use:
1. The left side of the module is the input port, and the right side is the output port
2. When controlling a single module, only the input port needs to be connected to the CPU
3. When multiple modules are cascaded, the input terminal of the first module is connected to the CPU, the output terminal is connected to the input terminal of the second module, the output terminal of the second module is connected to the input terminal of the third module, and so on.
