I think I fried an arduino pro mini (genuine) and I am trying to figure out what went wrong.
First I connected the pro mini to Arduino UNO and uploaded the blink sketch.
Then, I connected a 12V from an AC/DC adapter through the RAW pin with the UNO disconnected.
It worked for 10-20 seconds and then stopped. Now, If I connect it again to the power either 12V through RAW pin or 5V from the UNO through the VCC pin, gets really hot and of course doesn't work. The power led is on.
From what I understand, the board should be able to work with 12V. I checked the input voltage and it was OK.
What went wrong?
