A single module can drive an 8 * 8 common cathode lattice
With four screws hole, aperture 3mm, by using our M3 stud fixed.
Module with input and output interfaces, supports multiple modules cascade.
WIRING
The module left as an input port to the output port on the right.
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 ... 51 MCU, for example:
VCC → 5V
GND → GND
DIN → P2.2
CS → P2.1
CLK → P2.0
