ESP32 Forum

Hi,
from datasheet we can read that recommended minimum voltage for "regular" esp32 is 2.3V and for esp32 pico its 3.0V.
In other hand in menuconfig we dont have separate brownout level for pico, or i didnt see it. So my question is, with what voltage esp32 pico would trigger brownout:
- is it around 2.9-3.0V
- is it around 2.4-2.5V like its set in menuconfig?

Any help from hardware team, or should i ask on github?

It will be exactly the same. It's still the same ESP32, just packed into a tiny module.

It will specify a higher minimum voltage due to the integrated flash, which typically has a higher minimum than the ESP32 itself. The same will be true of WROOM modules, for example.

So there will be a ~500mV window where the supply voltage may be out of spec for the flash, yet too high for the ESP32's brownout detector to kick in. An external supervisor is always an option if there's any possibility of the voltage getting close to these thresholds.
