Hi,
My goal is as said, run my system at the lowest power I can.
I have an esp32, a dc-dc boost converter(from 3V battery to 3.3V) and some sensors.
These are 2 schematics I am considering:
1. Powering the esp32 from the 3V battery always and the sensors from the 3.3V - is it possible and correct to do so? Using an efficient dc-dc converter what magnitude of current do they take with enable off?
2. Switching between the power sources - when in active mode - esp32 is on the 3.3V, and when in sleep mode esp32 is on the 3V battery.
Which is better? Or there is a simpler alternative?
Thanks!
