A single module can drive a 8x8 dot matrix common cathode operating voltage: 5v
Dimensions: 128x128x13cm 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: Vcc 5v gnd gnd din p22 cs p21 clk p20
