Description:
- 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.
