Hi everybody,

I had a problem on my XIAO ESP32 S3, previously it was working fine, I could flash the camera_webserver example and get streaming for a while. At that time I found the board was very hot, then the com port suddenly didn’t appear. Tried connecting and reconnecting, or entering into Bootloader mode, but it still doesn’t work, the com port still doesn’t show up, the red led is flashing, and the board is still hot. After that I checked the 3v3 - GND pin, it turned out to be a short circuit. Does that mean the device is burned? Is it possible to fix it?

Hi there,
Sounds like it is toast, but try this first. unplug for a cooling period.
Hold the reset button down and plug it into the usb port while doing so.
Does it make the windows detected device sound?“ding”
If the camera module is not plugged in all the way it can get very hot. AFAIK.
use a heatsink on the bottom.

if what he says is true it totally sounds like a voltage regulator issue
