1. Lilly SW HAN LILLY ELECTRONICS E mail amazon lillyelectronics com User Manual 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 Step 1 About circuit connection there will be some trouble at the controlled end To control a 12V LED light for example please connect the positive and negative to the power firstly Please connect the positive on LED light with the positive of module And the negative on LED light can be connected to the switch 1 S1 Lilly SRWUHAN LILLY ELECTRONICS E mai amazonaiilivelectronics com lf there are other LED lights needed to be controlled you just connect the positive on LED light with the positive of module as well And the negative on LED light can be connected to the sw2. itch 2 S2 switch 3 S3 the switch 4 S4 in turn The connection of controlled side is easier We only need to connect the corresponding control port with Arduino sensor expansion board through a sensor cable In that way two 12V LED lights can be controlled by Arduino which as shown below Lilly SWUHAN LILLY ELECTRONICS E mai amazonaiilivelectronics com
