4 Channel One Four Route MOSFET Button IRF540 V4.0+ MOSFET Switch Module for Arduino Isolated Power Module

Product description

1.MOSFET is an electronic device with good switching characteristics, and is widely used in circuits that require electronic switching, such as switching power supplies and motor drives, and lighting dimming. Relay is another module with switching characteristics that everyone is very familiar with. However, because the working principle of relays generally relies on mechanical contacts to achieve the purpose of opening and closing, it will inevitably lead to a very short switching time. In the case of inability to work, the beeping sound when the contact switch is made is also an annoying thing in some occasions.

2.The 4-way MOSFET switch we designed can provide up to 4 groups of electronic switches, which are used to control different circuit modules. Affected by the working principle of MOSFET, this electronic building block can only be used to control DC circuits, such as DC LED screens, etc., and is not suitable for the control of AC circuits. The MOSFET switch can be used to control a 100V/33A DC circuit under extreme conditions, but the minimum DC voltage for control is recommended not to be lower than 9V.

3.In the circuit connection, the connection of the controlled end is a little more troublesome. Take the control of 12V LED strips as an example, first connect the power supply between the positive pole (+) and the negative pole (-);

4.Then connect the positive pole of the LED strip to the positive pole (+) of the module, and the negative pole of the LED strip to the switch 1 (S1);

5.If there are other LED strips that need to be controlled, just connect the positive pole of the LED strip to the positive pole (+) of the module, and connect the negative pole of the LED strip to switch 2 (S2), switch 3 (S3), switch 4 (S4) on;

6.The connection of the control terminal is much simpler. We only need to connect the corresponding control port with the Arduino sensor expansion board through the sensor connection line, and then we can control these 12V LED strips through the Arduino. In the experiment, we connected two LED strips.
