Re: AQ board suddenly dead. Help needed.
Posted: Fri Nov 21, 2014 2:18 pmHi guys,
I've checked the 3.3V line and it appears to be dead. My multimeter is not the best (sometimes its hard to make a good connection between probes and very small elements), but I get 0V reading from J7 and J6, and 0.2V reading on BOOT0. Which is strange, shouldn't it be the same everywhere? Anyways, it may be just my multimeter, it's hard to get good contact with small elements with these probes.
Thing to note is that the MCU gets hot/warm quickly.
I think I'll send the board to Jussi regardless, I don't think I would be able to check which component failed. Even if I would, I can't solder things that are so small!
