In most projects, relays are the first choice to drive large current devices. They require a certain amount of current to drive the internal coil to pick up contact. But for some microcontrollers, like the Raspberry Pi and other microcontrollers with a limited current GPIO, it can be hard to drive one or more relays simultaneously. The MOSFET power controller is a module which can drive a large current device with limited current GPIO. It works as a MOSFET relay or MOSFET driver. When you give it a digital high-level signal (3.3~10V), the MOSFET turns on, and vice versa. Compared to a relay module, a MOSFET power controller is compatible with Arduino, Raspberry Pi and other microcontrollers, and supports 3.3~10V logic power control. The VIN port supports 5~36V; 0~20A power input, if the current is over 10A we recommend an external heat sink. The MOSFET module also supports a quick ON-OFF switch, the switching frequency arrives at 1KHz. That's a good point for robot control! The MOSFET power controller comes with a standard PH2.0 3-pin Gravity interface. It makes the module compatible with the Arduino IO expansion shield. Note: works with direct current (DC) only!
