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.
   3. Plug in PoE ethernet; check voltages: 5V, 3v3 and Vpwr==5V
4. ESP32
   1. Solder in the ESP32
   2. Unplug PoE ethernet; plug in USB;
   3. Check 115200 baud visibility of ESP32 (press reset if needed). Should see

      ets Jul 29 2019 12:21:46 ... rst:0x1 (POWERON_RESET),boot:0x13 (SPI_FAST_FLASH_BOOT)

   4. Check upload with default Arduino example `Blink' app against LEDs set to OUT1/OUT2 (GPIO 16, GPIO4) with ESP32 -> ESP32-WROOM-DA module with settings and .
5. PoE and ESP32
   1. Remove from USB; plug into PoE and check LEDs still flash

Improvements

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