- Elecrow Crowtail MOSFET Module
- Enables you to control higher voltage projects
- Offers two screw terminals on the board
- Passes power from one end to another when closed
The Elecrow Crowtail MOSFET Module enables you to control higher voltage projects, say 50VDC, with low voltage, say 5V, on the microcontroller.

MOSFET is also a kind of switch. There are two screw terminals on the board. One for input power source and the other for the device you want to control. The Crowtail- MOSFET will pass the power from one end to another when closed. But if the outer power source is absent, your device can still draw power from the microcontroller via the Crowtail interface.
