Ok, Renders from
OSH Park. Seeking comments on layout.

All the connectors on the sides are the Molex connectors discussed above. Except the ones on the wider spacing at the top - they are standard Weidmuller wire connectors.
Board measures under 3" on a side, mounting holes are on a 2.5" center spacing. Makes the Teensy a little less teeny
Power is select-able:
- Teensy powers the board through USB power and onboard regulator. (Requires no SMDs)
- Teensy 250mA LDO receives power from 5V plugged into board. (requires a few SMD for reverse voltage and current protection.)
- Board gets 5V power from robot, runs through the breakout board's 1A 3.3V LDO regulator. (requires all the SMD components - 0805 or larger for easy soldering.)
In addition, there are four power selection banks for the IO, to allow 3.3V or 5V devices to be plugged in.
