ESP32-WROOM-32 module's power and ground pins showing connectivity

Postby Sai Teja » Mon Feb 05, 2018 6:51 am

I designed a development board based on ESP32-WROOM-32 . Initially everything worked well. But suddenly my ESP32 stopped working :( . After debugging, I found out that ESP-32 module's power pin (3V3) and Gnd pin showing connectivity. I don't know why this happened.

At what situation this happens? :roll: And please tell the precautions to avoid such conditions to happen.

Please help me in this regard.

What exactly do you mean with 'connectivity'?

I agree that is likely, but I'd like some more info: how did he measure it? Is the Wroom32 still in circuit? For all we know, he's charging a huge external capacitor with his multimeter and seeing that as a short.
