Electronic Building Block 4 Way Switch IRF540 Switch MOSFET Isolation Power Module Board
1. If other LED lamps strip need to be controlled, the positive pole of the LED lamp is connected to the positive pole of the module (+), and the negative electrode of the LED lamp is connected to the switch 2 (S2), the switch 3 (S3), and the switch 4 (S4).
2. We only need to connect the corresponding control port to the sensor expansion board through the sensor connection line, so that we can control the LED lights of these 12V. In the experiment, we received two LED lights
Please allow 1-3mm differs due to manual measurement.
