Arduino 4 Route MOSFET Button IRF540

MOSFET is an electronic devices with good switching characteristics. It is widely used in circuits, such as power supplies switching ,motor drives, lighting dimmer and so on. Relay is another kind of module with switching characteristics. Since relay works relying on mechanical contacts to open or shut. In this way it s will inevitably lead to relay's stopping working while switching time is too short. And papa sound made by relay in some situations is annoying.

We designed a 4-channel MOSFET switch. It can supply up to four groups of electronic switches to control different circuit blocks respectively. Limited by the working priciples, MOSFET can only be used to control the DC circuit, such as DC-LED screen and so on, but not suitable for AC circuit control.

In some extreme cases,It can be used to control 100V/33A DC circuit. However, it is suggested that the controlled DC voltage is more than 9V.

It takes some work to connected to the controlled part. Take controlling 12V LED lights as an example. First connect to the power through the positive (+) and negative (-).
Then connect the LED's positive(+) with the module's positive (+), and LED 's negative terminal is connected to switch 1 (S1):
If controlling other LED lights at the same time, connect LED's positive to the module's positive (+), and their negative terminals are in turn connected to switch 2 (S2), Switch 3 (S3), Switch 4 (S4):Connection on controlling part is much simpler. We need only connect the corresponding controlling ports to Arduino sensor extension shield through the sensor cable. Then we can control these 12V LED belt through Arduino. In the experiment, we pick up two LED belts: Test code is as follows:

int s1Pin = 6;
int s2Pin = 7;

void setup() {
  pinMode(s1Pin, OUTPUT);
  pinMode(s2Pin, OUTPUT);
}

void loop() {
  int i;
  
  digitalWrite(s1Pin, HIGH);
  digitalWrite(s2Pin, HIGH);
  delay(500);

  digitalWrite(s1Pin, LOW);
  digitalWrite(s2Pin, LOW);
  delay(500);
  
  for (i = 0; i < 10; i ++) {
    digitalWrite(s1Pin, HIGH);
    delay(500);
    digitalWrite(s1Pin, LOW);
    delay(500);
  }
  
  for (i = 0; i < 100; i ++) {
    digitalWrite(s2Pin, HIGH);
    delay(50);
    digitalWrite(s2Pin, LOW);
    delay(50);
  }
}

Good news : We have updated the old version of MOSFET switch module : Arduino 4 Route MOSFET Button IRF540 V2.0. Some customers leave us feedback that the MOSFET chips on the old version module are always bended and the feet are always broken. So we changed them all to SMD chips. Also, wire connection on this new version module becomes much easier. Compared with the shared positive terminal on the old version module, we add seperate terminal for each channel.
