T-OI plus ESP32-C3 Deep Sleep
-
I measured the current from the battery during deep sleep.
W/ red LED the current was 831 uA.
The red LED consumes (3.3 V - 1.85 V)/ 2 kOhm = 725 uA.
Cutting off the red LED would result in 106 uA.
Is it possible to reduce this current further? -
This may not be possible on the existing basis, and part of the current consumption should come from the power consumption itself

@lewis Here are my results of current consumption w/o red LED. The blog post is in German but Google helps.

The device works much longer now. It is a good idea to make the LED switchable in a redesign.
