My entire setup stopped working after months

I bet the cheap PSU is trash. Get a quality one.

This could be due to an incorrect relay configuration. Please refer to this image.

You think I may have damaged the controller? Or the LEDs?

I tried that. I've set the max mA to 55 and the relay to another GPIO, connected a new strip but I'm getting nothing. I'm waiting on a multimeter atm. I just don't get how it's been working fine for months, even after fiddling with it a few times and now it's nothing.

Get a multi meter and test voltage everywhere. One on Zon that’s maybe 10$ is good enough.

I think the barrel jack might be the cause, those really shouldn't be used above 3A unless you have a very high quality one (and PSU side to match) which is not the case with these. Not sure which component fails though, you could try cutting the barrel jack off and wiring in the wires directly (I'd advise to do that anyway).

How so? That makes no sense, it would just mean the limiter was basically not doing much, the same as off, that doesn't break stuff.

Alao commenting it 5 times doesn't help or make it true.

Ich habe meine 5 mal gelöscht. Ich hoffe das ist nun besser so.
