I am looking to use an aux channel on an RC receiver to switch several 12V LED lights on and off.
The lights are powered by a 12V 33a/h deep cycle battery.
Which item would be better suited for this? The “Basic SPDT Relay Carrier with 12VDC Relay,” or the “RC Switch with Medium Low-Side MOSFET.”
As Always thanks for your help.
The Basic SPDT Relay Carrier with 12VDC Relay that you mentioned accepts simple digital signals; if you are intending to use an RC signal, you should instead be considering one of our RC switches with relay. (Please note that the assembled version comes with a 5V relay so you can power it from a typical RC receiver, but it can still switch much higher voltages, including a 12V supply like you described.)
Either the RC switch with Medium Low-Side MOSFET or the RC Switch with Relay would probably be fine as long as they can handle the current draw of your load.
The RC switch with Medium Low-Side MOSFET would be more compact and have quieter operation. One potential advantage of the RC Switch with Relay is that the relay pins are electrically isolated from the logic side of the board (though that probably isn’t a major concern for just turning LEDs on and off). It also has mounting holes (which the RC switch with Medium Low-Side MOSFET lacks), so depending on your application, that might make it easier to physically add to your system.
Thanks for the reply. I appreciate Pololu’s customer service. It’s very helpful for those of us learning as we go.
