The rubber plug that was inside the button fell out when the button was pressed. I’m a bit devastated because I bought my esp32-s3 today and after only 20 hours it doesn’t work. Do you know where I can get such a button and someone can tell me how to solder something so small?
Hi there,
This seems to be a thing lately… I have two that have lost there button.
it’s the boot button so you can add an external one,with an alligator clip and test wire, connected one end to ground , so when you press it GPIO O is GND when you press it.

Not a solution but a temp fix for a couple resets to boot mode.
