IRF520 MOSFET DRIVER MODULE

The IRF520 MOSFET Driver Module is an essential break-out board designed to bridge low-power microcontrollers with high-power DC peripherals. Perfect for DIY electronics, robotics, and automation setups, this module allows devices like an Arduino, Raspberry Pi, or ESP32 to safely control high-current loads that exceed their native GPIO pin limitations.

Equipped with a robust IRF520N Power MOSFET, the board utilizes a pulse-width modulation (PWM) or standard digital signal to smoothly control DC motors, high-power LED strips, solenoid valves, or miniature heating elements. The module features an onboard status LED to give immediate visual feedback of the output state, and heavy-duty screw terminals to ensure secure, low-resistance wiring connections.

Technical Specifications

Electrical Parameters

Pinout & Interface Configurations

Control Side (3-Pin Male Header):

• SIG (Signal): Input trigger pin connected to the microcontroller’s GPIO/PWM output pin.

• VCC: Power input for the onboard circuitry (typically 5V or 3.3V matching logic level).

• GND: Common ground connection shared with the microcontroller.

Load Side (Screw Terminals):

• VIN / GND (Terminal 1): Connects to the external power supply for the high-power load (0V to 24V).

• V+ / V- (Terminal 2): Connects directly to the target DC peripheral (e.g., motor, LED strip).

Core Product Features

• PWM Speed & Dimming Control: Seamlessly handles PWM signal streams, enabling precise speed control for DC motors or smooth brightness dimming for LED strings.

• Microcontroller Protection: Acts as an electrical buffer, isolating your sensitive development board’s logic lines from high-voltage supply noises.

• Onboard State LED Indicator: Includes a miniature surface-mount LED that illuminates when the control signal is high, streamlining rapid circuit debugging and validation.

• Compact, Mountable Footprint: Features dual mechanical M3 mounting holes for solid fastening into custom control boxes or 3D-printed project enclosures.

Technical Note: For logic level inputs of 3.3V (e.g., ESP32 or Raspberry Pi Pico), the maximum output current will be significantly lower because the IRF520 is not a logic-level MOSFET and requires closer to 5V at the gate to fully open the channel. If driving loads above 1A, an external heatsink is strictly required.
