Crowtail - MOSFET

Crowtail - MOSFET enables you to control higher voltage project, say 50 Volt DC, with low voltage, say 5 Volt, on 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 device you want to control. Crowtail - MOSFET will pass the power from one end to another when closed. But if outer power source is absent, your device can still draw power from microcontroller via the Crowtail interface.

Crowtail - Mini Fan 2.0

This is a Crowtail mini fan with the mini motor driver which use the whole analog circuit.
