ESP32 don't start anymore
Posted: Sun Jan 14, 2024 10:23 am
Hello,
I made a custom PCB with a ESP32-ROOM-32 and after a few cycle of use, my PCB won't start anymore. Five of my ten mountig are not working anymore with the same symptom. The power supply is OK, but when i plug a serial programmer there is nothing on the output.
It seem the ESP32 don't start !
I swapped one of the ESP32 with a brand new one and the problem still persist, i think there is a design problem with my PCB but i don't know where
Here the design
Does anyone already have the same problem ?
Thanks a lot
Julien
