I'm trying to understand how everything on the Arduino Mega 2560 is wired but I cannot figure out why the highlighted resistors in my picture are there. Any insight would be appreciated.


Those are not connected. They are unused resistors that are part of little 8-pin packages  RN1, RN2, and RN3.

Thank you for the quick response CrossRoads!

What about for this section highlighted? Is it part of the 3.3v regulators circuit (I can't think of the name of that circuit, it eludes me this late) or is that just extra as well?
