Tutorial: How to use the FR120N Module

The FR120N module is an ideal MOSFET controller for current protection and control applications. Useful for beginner and intermediate makers.

What you need

• Arduino UNO or compatible
• 10kΩ resistor
• 5V power supply cable
• Ground cable
• Multimeter

Steps

1. 1. Install the FR120N module on a protected circuit.
2. 2. Connect the VCC to the 5V of the Arduino.
3. 3. Connect the GND to the GND of the Arduino.
4. 4. Connect the SGSN pin to pin 9 of the Arduino.
5. 5. Connect the DRAIN pin to the output pin of your load.
6. 6. Connect the GATE pin to a digital pin of the Arduino through a 10kΩ resistor.
7. 7. Check the maximum current specifications in the datasheet.
8. 8. Test the current at the DRAIN with a multimeter.

Example code

```void setup() {  pinMode(9, OUTPUT);}void loop() {  digitalWrite(9, HIGH);  delay(1000);  digitalWrite(9, LOW);  delay(1000);}```

Mini project

Create a simple protection circuit for a relay.

Common mistakes

• Connect the GATE to an Arduino pin without a resistor.
• Power the DRAIN with a voltage higher than 20V.
• Ignore the maximum current specification.
• Do not test with a multimeter.

Recommended accessories
