Itsy M0 getting hot

by Bekar_T on Mon Apr 26, 2021 12:56 am

I had to pick up an Itsy M0 I havent used for some time to run a code for experiment on another problem and it tripped a current draw alarm on the motherboard USB3 port.

When I unplugged it, the board was noticeably hot to the touch.

It's recognized and runs perfectly fine as far as I'm concerned but there's clearly a problem somewhere.

If my temperature senses are any accurate, main sources of heat were the chip itself and some components near the usb port.

I don't remember any problems with it the last time I used it so now I'm a bit confused as to what might have happened.

Inspect the board for any stray bits of wire or solder... anything that could be causing a short.

That was actually my first thought and I meticulously brushed the whole board with very soft toothbrush dipped in rubbing alcohol but that didn't change much.

Nothing is connected to the ItsyBitsy?

Nope, just the bare board connected to usb. Even when the code is done running, chip is still getting uncomfortably hot.
