MOSFETs are like little relays that don't wear out and don't make a sound when switching. This breakout board makes it easy to switch loads on and off using your favorite Arduino, Raspberry Pi, BeagleBone or PIC microcontroller. They can be used to turn high-drain loads on and off, like RGB LED light strings, motors, heaters etc.
The board uses 4 N-channel MOSFETs. While each MOSFET can each handle up to 37 Amps, the board and connectors can only handle 15 Amps. You can switch all 15 Amps through one output, or spread the current through all 4 MOSFETs - as long as the total current through the board does not exceed 15 Amps. You may damage the board or connectors if you exceed this limit.
The board has 4 outputs, so it is perfect for controlling RGBW light strings. It can also control 4 motors or 4 heaters ...
If you only need 3 outputs then take a look at this board.Specifications:
- Number of outputs: 4
- Maximum current per output: 15 Amps (limited by screw terminals and PCB)
- Maximum total current: 15 Amps
- High quality MOSFETs have incredibly low resistance of 0.01 Ohms. This means less heat!
- Maximum voltage: 30V DC
- Turn output on: 2.5V or higher (20V max)
- Turn output off: 0V
- MOSFET used: PSMN011-30YLC
- Dimensions: 2" x 1.6" (50mm x 40mm)
- 4 mounting holes, one in each corner
- Works with Arduino, Raspberry Pi, BeagleBone and other microcontrollers
- Connect pin D3 of Arduino to pin 1 on the breakout board
- Connect GND of Arduino to GND on the breakout board
setup() {
pinMode(3, OUTPUT); // Configure D3 as an output
}
loop() {
digitalWrite(3, HIGH); // Turn on the MOSFET
sleep(1000); // Wait 1 second
digitalWrite(3, LOW); // Turn off the MOSFET
sleep(1000); // Wait 1 second
analogWrite(3, map(26, 0, 100, 0, 255); // PWM the output to achieve 26% brightness
sleep(1000); // Wait 1 second
}
