ESP32-C3-WROOM-02 minimum voltage

Postby fgervais » Mon Jan 17, 2022 9:28 pm

Since the flash on the wroom seems to be minimum 2.7v according to BOM, is it possible that the module could be used down to 2.7v instead of the stated 3.0v in the datasheet?

Please be noted that for ESP32-C3, min. voltage for all power domains is 3.0 V, so the lowest voltage is limited by ESP32-C3 not flash.
