MOSFET Power Controller Module For High Current DC Load Switching Using Low Voltage Microcontrollers
The Gravity MOSFET Power Controller is a high-current switching module designed to control DC loads using low-current GPIO signals from microcontrollers and single-board computers. Unlike traditional relay modules that require significant coil drive current, this MOSFET-based controller can be directly driven by logic signals ranging from 3.3V to 10V, making it ideal for platforms such as Arduino, Raspberry Pi, LattePanda, Intel Edison, Intel Joule, ESP32, and other low-power controllers. It functions as a solid-state MOSFET relay, providing reliable and efficient control of motors, LEDs, pumps, solenoids, and other DC-powered devices.
The module supports a wide input voltage range of 5V to 36V and can handle currents up to 20A. For applications exceeding 10A, an external heatsink is recommended to improve thermal performance. Unlike mechanical relays, the MOSFET controller supports fast switching frequencies up to 1KHz, making it suitable for motor speed control, robotics, automation systems, and PWM-based applications. The integrated Gravity PH2.0-3P interface enables simple plug-and-play connectivity with Arduino IO expansion shields and Gravity-compatible development platforms.
