Introduction

In most Arduino projects, relays are the first and easiest choice to drive large current devices. It requires a certain amount of current to drive the internal coil to pick-up contact, ut for some MCU, like Intel Edison, Intel joule, lilypad, Raspberry Pi and other microcontroller with limited amount of current GPIO, it’s hard to drive one or more relays simultaneously.

The MOSFET power controller is a module which can drive a large current device with limited current GPIO. It works as a MOSFET relay or MOSFET driver. When you give it a digital high-level signal (3.3~10V), MOSFET turns on, and vice versa.

Compared to a relay module, MOSFET power controller is compatible with Arduino Raspberry Pi, Lattepanda and other Microcontroller and supports 3.310V logic power control. The VIN port supports 536V; 0~20A power input, if the current is over 10A, we recommend an external heat sink. Additionally, our MOSFET module supports a quick ON-OFF switch at a switching frequency of 1KHz. This is especially helpful in many robotic projects that require high precision drivers.

The MOSFET power controller comes with a standard PH2.0-3P gravity interface. It makes the module compatible with the Arduino IO expansion shield. In the the end the module is plug and play ready and easy to use.

const int LampControl=3;                   //define var
void setup() {
  pinMode(LampControl,OUTPUT);            // Set pinMode
}
void loop() {
  digitalWrite(LampControl,HIGH);//Light up lamp 2s
  delay(2000);
  digitalWrite(LampControl,LOW);//Turn off lamp 2s
  delay(2000);
}

Expected Results

The lamp will blink like an led (This is a demo, we do not suggest you operate your lamp like this continually, since it will reduce the service life.)
