KS0449 keyestudio 3-Channel IRF540NS Large Current MOS Module
Overview
The keyestudio 3-channel IRF540NS high-current MOS module uses 3-channel MOS switch, which is applied to operate the high-current with small current, similar to a relay element.
It can be applied to drive the Servo, high-current LED light, etc.
When using, input the voltage less than 40V to the terminal block VIN GND, the voltage of V+ block is equal to VIN block.
We can control the HIGH or LOW of NA NB NC pin headers to determine whether connect to ground.
When at HIGH, NA- NB- NC-pin headers are connected to ground, D1 D2 D3 led will turn on; when at LOW, NA- NB- NC-pin headers suspend, D1 D2 D3 led will turn off.
The module comes with four 3mm fixing holes, easy to fix on any other devices.
Special note: this module only supports 5V microcontroller rather than 3.3V microcontroller.

PINOUTS
Connection
Test Code
int BASE = 4 ;
int NUM = 3;
void setup()
{
for (int i = BASE; i < BASE + NUM; i ++)
{
pinMode(i, OUTPUT);
}
}
void loop()
{
for (int i = BASE; i < BASE + NUM; i ++)
{
digitalWrite(i, HIGH);
delay(2000);
}
for (int i = BASE; i < BASE + NUM; i ++)
{
digitalWrite(i, LOW);
delay(2000);
}
}
Test Result
Done uploading the code, powered on, when NA- NB- NC-pin headers are successively connected to ground, D3 D2 D1 led will successively turn on; then NA- NB- NC-pin headers successively suspend, D3 D2 D1 led will successively turn off, alternately and circularly.
