The Gravity 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), MOSFET turns on, vice versa.
Compare to the relay module, MOSFET power controller is compatible with Arduino, Raspberry Pi, Lattepanda and other Microcontroller, 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. And MOSFET supports quick ON-OFF switch, the switching frequency arrives 1KHz. That is a good point for robot control.
The MOSFET power controller comes with a standard PH2.0-3P gravity interface. It makes the module compatible with the Arduino IO expansion shield. Plug and play, easy to use.
