That's exactly my fear... Maybe now is working but one day it will not boot because something did burn...
Can it be?
Thanks

WS2812B LEDs have Hi-Z inputs, so cannot draw any significant current (if powered).

Yes, I mean your "small resistor from 3v to TX".

I don't wrote "voltage regulator". I wrote "voltage translator".
