So I am looking at the Teensy 3.2 schematic, and I have two questions. Does the Teensy 3.2 include a 100uF capacitor and does it include a 32.768kHz crystal? I see they are greyed out in the schematic, and I was wondering why they are greyed out, I only see one crystal on the board and I don't think I see a 100uF capacitor. I highlighted the components in question in red on the schematic.
