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 P2.2
CS P2.1
CLK P2.0

Size for manual measurement, there may be a 0 to 2 cm error, belongs to the normal phenomenon.
