Get 5uA current with the esp32 devkit

[fer_di]

Hello,

The Esp32 datasheet specifies that the "hibernation mode" (RTC On only) consumption is 5uA.

However I can't find any Deep Sleep tutoriel using the Esp32 devkit getting under 150uA.
This article even explains that ESP32 consumption can't get under 10 mA using dev board.
(https://www.instructables.com/id/Batter ... SP-Design/)

Do you know if the 5uA consumption goal is achievable on Esp32 devkit ?

It depends on the devkit. For instance, a fair amount of devkits use AMS1117 voltage regulators, and as these have a quiescent current of 5mA average (and up to 11mA max), you'll never be able to get anything under that.

happy new year together,

yeap - this is true.
