Description

Wiring Instructions:
A single module can drive a 8x8 dot matrix common cathode
Operating Voltage: 5V
Dimensions: 12.8X3.3X1.3cm(5.04X1.3X0.51in)
Fixing screws with 64 holes with a diameter 3mm
Module with input and output interfaces, support for cascading multiple modules
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
