My external AMS1117 (3V3) regulated 3.3V DC blew off twice on connecting to the evaluation board.
Resistance measured between VCC and GND was only around 14 ohms.
I suspect the powerline capacitors (2 each) connected to pins 11, 17, 26, 35 must have gone bad.
Please see page 8 in the user guide.
I there by any chance this might be true?
It came to me for the same topic. So I just copy the link below where we discussed this issue.
