I am trying to get ESP201 in deep sleep to use as little as possible.

This is how things are connected:


V REG is voltage regulator to go to 3.3V (idea is to use 4 x NiMH 1.2V AAA rechargeables)

When measuring current draw (V Reg is bypassed and I am powering ESP201 using 3.3V and GND pins on additional header connector ) in deep sleep mode I am always around 3.43 mA. In all discussions this should go to micro amps territory.
What am I doing wrong ?

Thanx,
DiNo

And also about where exactly you measured the drawn current?
And offcourse update your schematic to reflect the actual situation!
I think I can name the culprit but first have to really know all parts in the game ....

- Sun Aug 21, 2016 5:06 pm #53522 Did you disable/remove/whatever the power led?
3.5mA look just like the obvious led current ...
