    One more quick question: What would be the appropriate pin to solder a ground connection to? I’m setting up an I2C connection between two Arduinos (one being the Backpack) which requires that their grounds be connected (along with analog pins 4 and 5 too, but I know where those are).

    Should I just solder to pin 8 or 22 on the ATmega328’s pads?

    Awesome, that’s what I was hoping for. I don’t have a problem with soldering a breakout cable or something directly to the ATmega328 😉
