MOSFET Relay Power Controller Module (DFRobot Gravity)

AED 29.00



This switch provides control over devices requiring substantial current via a microcontroller, functioning akin to a relay utilizing a MOSFET transistor. It operates within a voltage range of 5V to 36V, capable of handling currents up to 20A (with a recommendation for an additional radiator beyond 10A). The digital signal from the control system, ranging from 3.3V to 10V, toggles the switch's state. Compatible with various microcontrollers like Arduino or Raspberry Pi, it comes with a cable tailored for Gravity DFRobot IO Expansion Shield.
