Description:
The DFRobot Gravity: MOSFET Power Controller addresses a common challenge in microcontroller projects: driving high-current devices with limited GPIO output. While relays are traditionally used, they require a significant current to activate their coils, posing a problem for microcontrollers like the Intel Edison, Intel Joule, Lilypad, and Raspberry Pi, which offer lower GPIO current capabilities.
This module acts as a highly efficient electronic switch, utilizing a MOSFET (Metal-Oxide-Semiconductor Field-Effect Transistor) to control high-current loads. Think of it as a solid-state relay or MOSFET driver offering superior performance and versatility. Applying a digital high-level signal (3.3V to 10V) to the control pin instantly activates the MOSFET, allowing current to flow to your connected device. Conversely, a low-level signal turns the MOSFET off, halting current flow.
Unlike mechanical relays, the MOSFET Power Controller is fully compatible with a wide range of microcontrollers, including Arduino, Raspberry Pi, and LattePanda, thanks to its 3.3V to 10V logic level compatibility. The power input (VIN) supports a wide voltage range of 5V to 36V and can handle currents up to 20A. For currents exceeding 10A, an external heatsink is recommended to ensure optimal performance and prevent overheating.
Note: It works with direct current (DC) only!
