Gravity: MOSFET Power Controller 5-36V/20A

A switch that allows you to control a device requiring a large current by using a microcontroller. It works as a relay based on transistor MOSFET. It works with voltage from 5 V to 36 V with current consumption of up to 20 A (at a current higher than 10 A, it is recommended to use an additional radiator). The digital signal of the control system in the range from 3.3 V to 10 V changes the status of the switch. It can be controlled by any microcontroller, e.g.ArduinoorRaspberry.The kit includes a cable adapted to Gravity DFRobot IO Expansion Shield.

The product is compatible with Arduino

Sample code and detailed information can be found inthe user's guide.

The device can also be controlled by the ON-OFF switch that has a switching frequency of 1 kHz.

The module works with any microcontroller with digital inputs, includingArduino. For this you need to connect the power supply and ground, and any digital pin of the microcontroller. On the other side of the module, you need to connect the managed device.

Example of connecting the sensor withArduino.
