Keyes IRF520 MOSFET Driver Module - DC Motor Fan LED PWM Control for Arduino

Keyes IRF520 MOSFET Driver Module - PWM DC Load Control for Arduino and ESP32

The Keyes IRF520 MOS Module is a widely used N-channel MOSFET driver board for controlling DC motors, fans, LED strips, pumps, solenoids, and other high-current DC loads from a low-power microcontroller PWM signal. Built around the IRF520 power MOSFET, the module provides screw terminal load connections (V+ and V−), a dedicated VIN/GND power input terminal block, and a 3-pin SIG/VCC/GND control header for direct Arduino, ESP32, and Raspberry Pi connection.

Key Features

• IRF520 N-channel MOSFET - handles DC motor, fan, LED strip, pump, and solenoid loads
• Screw terminal load output (V+ and V−) - secure load wire connection without soldering
• Screw terminal power input (VIN and GND) - separate load power supply connection
• 3-pin control header (SIG, VCC, GND) - direct connection to Arduino, ESP32, and Raspberry Pi GPIO
• PWM compatible - control motor speed and LED brightness by varying duty cycle
• Keyes brand - trusted Arduino-compatible module manufacturer
• Compact red PCB - standard Keyes module footprint for easy breadboard and project use
