Description: RF520 Mosfet Driver Module

Specifications:

Here is a simple breakout board for the IRF520 Mosfet. Easy hookup to your Arduino or other 3-5v micro controller. Pulse current through a PWM pin, and use this to control a pump, LED, or other DC device at up to 24v, and ~5A. You can check the specs here.

Real simple to use: The simplest way of explaining how this little board works is this: You connect the power for the device you want to control to the Vin and GND. You connect your device to the V+ and V- screw terminals. When the SIG line is HIGH, a little LED lights up, and the GND is 'connected' to the V-. When the SIG line is LOW, the LED turns off, and the GND becomes 'disconnected' to the V-. The V+ and Vin are continuously connected.

You can power this device from your Arduino, VCC goes to the 5V connection, and GND to the GND pin on your Arduino.

Features:
 

• Voltage: 3.3V, 5V
• Output load voltage :0-24V
• Output load current: <5A (1A and above requires a heat sink)
• Platform: Arduino, MCU, ARM, Raspberry PI.
• Using original IRF520 Power MOS, you can adjust the output PWM.

Specifications

The power pins are as follows:

• VIN. The input voltage to the Arduino board when it's using an external power source (as opposed to 5 volts from the USB connection or other regulated power source). You can supply voltage through this pin, or, if supplying voltage via the power jack, access it through this pin.
• 5V.This pin outputs a regulated 5V from the regulator on the board. The board can be supplied with power either from the DC power jack (7 - 12V), the USB connector (5V), or the VIN pin of the board (7-12V). Supplying voltage via the 5V or 3.3V pins bypasses the regulator, and can damage your board. We don't advise it.
• 3V3. A 3.3 volt supply generated by the on-board regulator. Maximum current draw is 50 mA.
• GND. Ground pins.
• IOREF. This pin on the Arduino board provides the voltage reference with which the microcontroller operates. A properly configured shield can read the IOREF pin voltage and select the appropriate power source or enable voltage translators on the outputs for working with the 5V or 3.3V.
