Cheerio my friends, building a 2.4 and still not done.
I went for SB, Tap, Rapido hotend and a Fly SB2040 including UTOC board.
When I tested the hotend without LED, everything works fine. Hotend heats up, all sensors seem to be working. As soon as I connect the Neopixels to it, my SB2040 throws sparks. The first time I thought I had got the wiring of the LEDs wrong, therefore I tried it a second time with a new SB2040 and new LED string. The same happened, the chip throws sparks. The picture shows the component that will be fried (picture shows board being intact...)
I run the SB on 24V.
Question: Is there anything obvious I havent noticed? Is that a typical error? Dont want to do this a 3rd time...
Also: Do you know what type of component that is? Would like to repair the boards if possible
