In the Teensy 3.2 schematic there are a few random wires that don't connect to anything. On the nets which connect the USB connector pins 2, 3, and 4 to name a few. What are those supposed to be?
The pinout images show TX1, RX1, and other functions duplicated on multiple pins but grayed-out. Can you reconfigure Serial1 to use either pins 0 & 1 or 5 & 21?
What is the purpose of the secondary smaller microcontroller on the Teensy? At first I thought it might be acting as a USB-UART converter (like an FTDI) but it isn't connected to the USB.
The silk screen around the surface pads for pins 29-33 and 28-24 implies that there might be a 0.1" pitch header that can be soldered on so that those pins could be brought down to a mother board socket. Is there a recommended part to use for that?
