Early 2025; version 1.14 variation of the PowerNode White: order of 15 units; 25/01/23 fab date; see also this page on configuration details.

NodeWhite - Blue boards; 1.14, Front NodeWhite - Blue boards; 1.14, Back

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. Solder in RJ45 connector
    2. Place solder bridges Vpwr, V5 to VPOE/VPOE5 in Source field
    3. 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. Plug in PoE ethernet; check voltages: 5V, 3v3 and Vpwr==5V
  4. ESP32
    1. Solder in the ESP32 -- revision used:
      1. Chip is ESP32-D0WD-V3 (revision v3.1)
      2. MAC: 08:a6:f7:b0:72:ac
    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. Uploading at 115200 should work.
      1. If it fails - go drop speed
      2. For proper board with proper/non-counterfeit chips - 921600 baud works stable and well.
      3. Check the schematic for the 33 Ohm resistors that are supposed to help with the impedance/driving.
  5. PoE and ESP32
    1. Remove from USB; plug into PoE and check LEDs start flashing as soon as the power LED comes on.
  6. From this point on - use a Galvanic USB isolator when connecting to the board with Ethernet plugged in.
  7. Solder in Buzzer, OLED display (if needed), buttons, connectors
    1. Test with plain PowerNode install & check screen & menu cycling
  8. Check RDIF
    1. Holding an RFID card should cause two beeps. Use the VNA - Vector Network Analyser with this information to check.
    2. Check IP allocation on screen/serial and check web interface
  9. (Optional) solder on final power selection, fuses, sensors, etc.

Problems during bringup

  1. Accidental solder bridge between pin 13/14 of ESP32 made it look like the switch was not mechanically not working (stuck in 0).

Test script for the (newish) AW chip

  1. include <Adafruit_AW9523.h>

Adafruit_AW9523 aw;

int I2C_SDA = 05; // 21 is the default int I2C_SCL = 15; // 22 is the default int IRQ_PIN = 35;

bool _irq_seen = 0; void irq() { 

 _irq_seen = true;

};

void setup() { 

 Serial.begin(115200);
 Serial.println("Adafruit AW9523 test!");
 Wire.begin(I2C_SDA, I2C_SCL);

 if (! aw.begin(0x58)) {
   Serial.println("AW9523 not found? Check wiring!");
   while (1) delay(10);  // halt forever
 }

 attachInterrupt(IRQ_PIN, irq, CHANGE);

 Serial.println("AW9523 found!");
 for (int i = 0; i < 16; i++) {
   aw.pinMode(i, INPUT);
   aw.enableInterrupt(i, true);

 };
 if (0)
   for (int j = 0 ; j < 50; j++)
     for (int i = 0; i < 16; i++)
       aw.digitalRead(i);

}

void loop() { 

 if (_irq_seen) {
   _irq_seen = false;
   Serial.println("IRQ");
 };

 static unsigned long lst = millis();
 if (millis() - lst < 200)
   return;
 lst = millis();

 for (int i = 0; i < 16; i++) {
   Serial.print(aw.digitalRead(i));
   if (i % 4 == 3) Serial.print(".");
 };
 Serial.println();

}

Improvements

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