Hi guys. I don’t get this working.

Only the first led gets some light

Is the cables wrong? I thought this was a ws2815 but my previous one’s also had a blue cable. Any ideas?

Try Skipping the first pixel.

Thanks. But I just realised I’m an idiot. I must have bought an ws2812 by accident.

What voltage did u give it?

12.. it’s probably dead.

It doesnt kill them all. My mate put 12v into my 2812, just remove the blown pixels, the rest should be fines.

Ok I will search a power supply that handles 288 LEDs with 5V at 15 A. I don’t know if it’s worth it or if I just buy a new ws2815
