Can drive an 8 x 8 common cathode lattice
Module with input and output interfaces, supports multiple modules cascade
The left of the module has an input port and the right an output port
The control of a single module, simply input port to the CPU
Multiple modules cascade input termination CPU, 2 output termination module, a module of the input of the input terminal, the output terminal of the first two modules of the first three modules, and so on
