Board Schematic

The most recent rev B schematic:

Changes:
- remapped teensy pins to the ones used by the teensy neopixel library
- added jumper options to connect LED string 4 to all four strings, and disconnect those from the circuit
- added 5th LED string connector for the sensor stem thing
- reserved necessary pins
- removed overcurrent detect circuit because I didn't have a chance to test it, replaced with a PTC footprint which should be lesser risk
- moved teensy main power to the input side of the load switch
- added place to measure full load current
- moved power supply mtg holes based on measurement of physical unit.
- enlarged elec cap pads for easier hand soldering
