Powered a 5V WS2811 LED strip with 12V by accident. It turned on for a split second, it fried a microcontroller, I noticed the smell and turned everything off as fast as I could.
When i tried powering the LED strip again with 5V (also exchanging for a new microcontroller of course) only the 2nd LED in row turned on. I cut off the first 3 LEDs and soldered the wires on again, but now nothing turns on.
Does that mean the whole 5m LED strip is busted or is it possible some LED+ics further down the line could be salvaged?
