exit status 1
Development board Arduino Nano compilation error.

This report would have more information with
"Show verbose output during compilation"
option enabled in File -> Preferences.

Enable verbose compile, try again, and post the output here.

Why is there a battery and circuit connected to the 3.3volt pin?

That is a (weak) supply output.
Leo…

Regardless of what's wrong with the schematic, it's not even compiling.
