Trying to understand power part of circuit....
Just to let you know I am not an electrical engineer but do dabble in electronics and there is no better place to learn circuits and how they work than to look at other people designs.
With that in mind I am trying to understand why the Pinetime watch has 2 voltage regulators...the ME6206 which takes battery voltage and regulates to 3.3V and the SGM2036-3.3 which also does the same?  The output for each is Vcc and Vdd and some components take Vcc and others Vdd.
I think it might have something to do with with the P24 power control and saving power and disabling some components when not in use, but that part of circuit eludes me also.

Very interesting question!

I've also been a bit puzzled by all the NC components and what benefit the P24 circuit would bring it it had been populated. Come to think of it, given the way so many footprints were included on the silkscreen I'm also a little curious why I cannot find the gaps for the unpopulated components.

On other words, I can't really answer but am definitely interested!
