Powering ESP32 module directly

Postby buster » Sun Jan 24, 2021 11:47 am

Hello,

I have used a development board like this: Image

Everything works perfect but now i want to use the WRover module without this board.

I tried to connect 3.3V from a bench power supply but the module won't start. I read something about GPIO0 and EN pin but i cannot find any information on how to start the EPS32 WRover without the development board.

I am sorry but i am really new to ESP32.

Did i forget something or should it work with just connecting 3.3V to the 3.3V pin and 1 ground to the ground pin?

Thanks a lot!
