I have a small circuit board connected to my ESC that can be powered on via pressing a button on the remote and then it gives 12V on three outputs to switch on lights (headlights and taillights). Due to shocking for years, this small panel has come to its end of life…erhhh…became broken. I want to buy a new one but not quite sure how to look for this…especially not as an eskate part. What do you guys think about it?
The capacitors and the coil are broken. There is no extra batter connector whatsoever. The three-pin connector on the top comes from the ESC and only pumps (I guess) electricity to this panel once it is triggered by the remote. Then, on those small ph2.0 connectors, 12Vs come out and operate LED lights.
If someone has experience with such LED/light control boards, I would appreciate to have advice on (and link to a listing) what to buy.

But as you can see, it has a separate battery connector and a switch. I think I don’t need a switch as the battery connector part is cut OFF or switched on when the remote triggers it.
That is some step-down or step-up converter. Without knowing more about the ESC and the lights, it’s impossible to say precisely what is going on. Usually, for light, you use the battery for power and then step down the voltage. It could be one wire is pass through from the battery, one is ground, and one is an on/off voltage. There are other possibilities, though. You also need to know how much total current is needed for the lights. I’d check the voltage on all 3 leads from the ESC with the lights on and off, and also measure the current to each of the lights when you put 12 V to them as a starting place.
If the company that made this still exists, getting a direct replacement from them is likely the simplest way to do things. Otherwise, you may have to do some work if you still want the switch to turn the lights on and off using the ESC.
Thanks, yeah i noticed that. I just don’t think I want to solder 10 cent parts on a 1-2 dollar mainboard. It is not worth the effort especially that I am not the best in soldering.

I do believe that it is just a step-down DC-DC converter from 36V → 12V. The controller part is not part of this module, it is part of the ESC. So once the ESC is triggered, electricity flows to this converter. I will check that input 3-pin cable as I have a guess the third wire is blind (i.e., it’s just a placeholder). Then, I try to get a newer design for the step-down element, which is more compact. The skateboard per se was made 3-4 years ago, and the company went missing within a year. So, I have already made some customization to the board. Hopefully, this light issue will be solved then too.
There are 2 in the front and 2 in the back. So all in all 3W each, 12Volts would mean a total of 1A. So a simple 36V->12V DC-DC converter like this: https://www.aliexpress.com/item/1005005505907937.html should do the job (after selecting the appropriate Volts).
I would just solder all cables to the output instead of taking the trouble with those ph2.0 connectors…they just consume a lot of space
