We can ignore the reserved pins. They aren't used. I'd like to avoid that we do use them unless we understand what flex we give up though.
The PCB should have a white triangular mark next to J1.1 if possible. It's the indicator for the mounting direction (because the connectors are symmetrical, it's easy to mount the wrong way around).
On the analog board, optional BoosterPack breakout edge connectors are available to add user interface elements.
These aren't isolated from the LaunchPad.
