Hi,

Thanks a lot for your answer, i soldered 0.1uf capacitor (don't have 1uf) with no result. Still nothing in serial.
I ordered 1uf capacitor in order to make more test

According the documentation and existing PCB, i didn't difference exept the capacitor between EN and GND

Thanks
Julien

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.
