So far so good. Everything works as expected but there are a few minor problems.
- Typo on silkscreen label on the breakout header for A9/D23. Appears as A9/D32.
- Through hole solder pads on the Teensy breakout are too thin.
- Holes for the surface pads on the Teensy 3.2 are useless and not connected to anything. Should probably be replaced with some proto holes.
