How to Use the MOSFET Driver Module IRF520

Wiring steps

1. Connect the module ground (GND) to your system ground.
2. Connect the module VCC or supply input to the load power supply (5V to 24V depending on your device).
3. Wire the load between the positive supply and the MOSFET drain (module output) so the MOSFET switches the ground side.
4. Connect the control pin to a PWM-capable GPIO pin on your Arduino or to a PWM output from a Raspberry Pi (use a suitable level-shifting or driver circuit if needed).
5. Power up the system and vary the PWM duty cycle to control motor speed or LED brightness.

Practical tips

• For currents near the upper rating, mount the module where it can dissipate heat or add a heatsink to the MOSFET.
• Use a separate power supply for motors and high-current loads to avoid voltage dips on your microcontroller.
• Add flyback diodes for inductive loads such as motors or solenoids to protect the MOSFET from voltage spikes.
• Keep wiring short and use adequately sized wires to reduce voltage drop and heating.

Safety and Compatibility Notes

While the IRF520 module is widely used with Arduino and Raspberry Pi platforms, the IRF520 MOSFET may not be a true logic-level MOSFET for heavy loads at only 5V gate drive. For best performance at 5V logic levels and sustained high current, consider adding a gate driver or choosing a MOSFET specified for logic-level operation. Always ensure correct power ratings, proper heat dissipation, and protective components when switching high-current loads.
