Wring:

• Left:
  Input,
  Right: Output
• Connect the Input interface to the CPU when controlling one module
• When controlling multiple modules cascade, connect the input interface of the 1st module to the CPU, connect the output interface of the 1st to the input interface of the 2nd, connect the output of 2nd to the input of 3rd, and so on..
• for example (51 MCU):
• 1) VCC -- 5V
• 2) GND -- GND
• 3) DIN -- P22
• 4) CS -- P21
• 5) CLK -- P20
