hmm..good to know.. (still learning it all I guess)
on this project.. (which is based/built form the SECOND image)..
there is no Electrolytic caps even being used (guess that is in incorrect).. I didnt see any +/- in the schematics..where others 'did' have it
here is the board made from it:

I havent had 'any' problems with anything so far with it.. as far is it not working/flashing bootloader/loading a sketch/playing audio..etc..
and again.. no electrolytic caps were used?
(elec caps are SO big!.....how to keep small footprint down when I see boards like/similar to this then)?
I am basically still learning.... I looking at open source schematics.. read, copy..trying to understand and implement into my own boards..etc
so thanks for the help/feedback..
Im sorta wondering why when I posted the first (full) schematic for review here, everyone said it was 'ok'??
take care
thanks!
