Arduino Leonardo, Grounds
« on: May 05, 2013, 04:32:58 pm »
I was studying the schematic for the Arduino Leonardo and something caught my attention. R3 ( and  R2 ) are marked as NM and no other value. What are these resistors and what are they for? Why are the ground not just tied together directly? :-/O
