IRF520 MOSFET Module board.

The module is designed to switch heavy DC loads from a single digital pin of your microcontroller. Its main purpose is to provide a low-cost way to drive a DC motor for robotics applications, but the module can be used to control most high-current DC loads.

You can use this module to switch a common negative with high currents easily by only using 5V volts. This unit can be used with a microcontroller as long as the microcontroller can give 5V out.

IRF520 MOSFET Module board Specification:

• IRF520 MOSFET, the gate can be driven via PWM output
• Allows Arduino to drive up to 24V loads, such as LED strips, DC motor, micro pump, and solenoid valves
• Voltage: 3.3V/5V
• Interface: digital level
• Output load voltage: 0~24V
• Output load current: < 5A
• Suitable for Arduino, SCM, ARM, and Raspberry Pi

IRF520 MOSFET Module board sample code:
You can simply use the Arduino basic blink sketch to get started and connect the signal pin on the Mosfet board to Arduino digital pin13.

void setup() {
// initialize digital pin 13 as an output.
pinMode(13, OUTPUT);
}
// the loop function runs over and over again forever
void loop() {
digitalWrite(13, HIGH); // turn the LED on (HIGH is the voltage level)
delay(1000); // wait for a second
digitalWrite(13, LOW); // turn the LED off by making the voltage LOW
delay(1000); // wait for a second
}
