Initial Bringup / checkout

Board 001 (selected as sacrificial):

  1. Optically checked soldering/board as is
  2. Plug in USB-C
    1. Check 3v3 and 5v power; check red LED comes one.
    2. Check for magic smoke/things getting hot (nothing should)
    3. check detection of serial port/driver. It won't have any output at this point
  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 Arduino blink check and Arduino blink code.
  5. PoE and ESP32
    1. Remove from USB; plug into PoE and check LEDs start flashing as soon as the power LED comes on.

From this point on - use a Galvanic USB isolator when connecting to the board with Ethernet plugged in.

  1. Solder in Buzzer, OLED display (if needed), buttons, connectors
    1. Test with plain PowerNode install & check screen & menu cycling
  2. (Optional) solder on final power selection, fuses, sensors, etc.

Improvements

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