Connection drawing:

We suggest you using a diode connectiong to the VCC in series. In order to prevent from damaging chip of Power Reverse or Voltage Fluctuation. ( The board does not add diode because the power would not enough to pull-in the relay for the buck from diode when power is too low. )
