MOSFET Driver Module IRF520 DC 3.3V 5V 5A MOSFET Button Driver Power MOS PWM Dimming LED For Arduino MCU ARM Raspberry PI

Description: MOSFET Driver Module IRF520 DC 3.3V 5V 5A MOSFET Button Driver

This little module is a breakout board for the IFR520 MOSFET transistor (Metal Oxide Semiconductor Field-effect Transistor), a module can adjust the output PWM. 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. Screw terminals are provided to interface to your load and external power source. A LED indicator provides a visual indication of when your load is being switched.

Specification:

• Voltage: 3.3V, 5V
• Output load voltage :0-24V
• Output load current: <5A (1A need to add more heat sink)
• Platform: Arduino, MCU, ARM, Raspberry Pi
• Using original IRF520 Power MOS, you can adjust the output PWM.
• Drive up to 24V allows the load, such as LED lights, DC motors, miniature pumps, solenoid valves.
• PWM dimming LED can be used to achieve step less dimming, variable speed motor control

Instructions:

• PWM signal for high level effectively
• When the PWM for high level (3.3 V to 3.3 V) :
• As the power supply voltage, between V + and V – working indicator, work load
• When the PWM is low level (0 V to 0.5 V) :
• V + and V – between 0, work lights out, don’t work load

Module Connections:

The connectors can look a bit confusing at first, but hook-up is fairly straight forward. The attached schematic can help clarify things.

To hook-up:

• Connect the load to be controlled across the V+ and V- terminals observing the correct polarity.
• Connect the power supply (up to 24V) across the Vin and GND terminals.
• Connect the uC ground and control pin to the GND and SIG header pins on the module. The center pin on the header marked ‘VCC’ is not connected.

The ‘SIG’ control input is active HIGH and 5V compatible, but can be driven as high as 10V to drive the IRF520 into full saturation. There is a green LED that lights when SIG is active HIGH

A 1K pull-down resistor is included on the module to help to ensure that the transistor will be in the off state when the microcontroller is powering up and the outputs are floating.

1 x 3 Male Header

• SIG = Signal input (active HIGH). Typically used with 5V logic. Can be driven at up to 10V to fully turn on the IRF520.
• VCC = No connection
• GND = Digital ground.

1 x 2 Screw Terminal (Load)

• V+ = Connect to positive lead of load (motor, LEDs, fan, etc)
• V- = Connect to negative lead of load

1 x 2 Screw Terminal (Power)

• VIN = Connect to power supply (0-24V) being used to power the load
• GND = Connect to power supply ground

Applications:

• LED lights dimmer, variable speed for DC motors, miniature pumps, solenoid valves

Package Include:

• 1 x MOSFET Driver Module IRF520 DC 3.3V 5V 5A MOSFET Button Driver
