If you need to control the DC power, a MOSFET is what you need. This is a very common PCB mount MOSFET switch with very low on-resistance and a control voltage (aka gate voltage) that is compatible with any 1.8V~30V microcontroller or mechanical switch. This allows you to control high-power DCdevices with microcontrollers.
This board has an opto isolator to protect your microcontroller from high currents.
With this MOSFET switch module, you can create project for control and switch of HIGH DC LOAD for max 100V 15A/33A, like DC motor, high power LED, fan.
