Hey there,
I have a Teensy 4.1 which was working fine. I was working on other projects for a while and now that I wanted to use it again, it doesn't seem to work any more. I tested it with a multimeter and there's no voltage on the 3V pin. 5V is there, so the USB connection seems to be fine. The fuse is fine, too. There's 5V on two pins of Q1, and nothing on the third. Am I correctly assuming there should be 3.3V on this pin? Is there anything I can do to save it, or is it gone? I'm kinda confused what could have happened, since I just had it connected to a computer 3-4 times, didn't solder anything to it and it was just lying on a shelf in the meantime. How fragile are they?
Thanks for any help.
