Electronic building block 4-way switch MOSFET switch IRF540 isolated power module

If there are other LED strips to be controlled, just 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 2 (S2), switch 3 (S3), switch 4 (S4):

The connection of the control terminal is much simpler. We only need to connect the corresponding control port to the sensor expansion board through the sensor cable to control these 12V LED strips. In the experiment, we received two LED strips:
