Initial Bringup / checkout

Board 001:

1. Checked soldering/board as is.
2. Plug in USB-C
   1. Check 3v3 and 5v power; check red LED
   2. check detection driver
3. PoE powering
   1. Place solder bridges Vpwr, V5 to VPOE/VPOE5 in Source field
   2. Do not place the Vpwr/5V bridges in the PoE field - these should be better labeled: e.g. have an 'OFF' text added to them like the one just above.
4. ESP32
   1. Solder in the ESP32

Improvements

1. Add the word 'OFF' to the labels of all bridges in the PoE field (and not just the top one)
