MIKROE-3337, Opto 4 Click Board is a galvanically isolated power switch, which uses a power MOSFET in combination with an optocoupler. The power MOSFET can withstand significant current due to its low ON resistance, allowing this Click board to be used with different kinds of power demanding applications. In addition, this Click board is equipped with the voltage limiting circuit, which cuts off the power supply when the voltage of the externally connected power supply suddenly drops. The galvanic isolation of the optocoupler offers protection of the controller circuit, thus preventing power surges from the controlled circuit
