Assembly

  • Solder 2x12 pin headers to the photon pins.
  • Solder the resistor onto the board.
  • Solder a DS18B20 sensor to the board using a cable / wire. Make sure it's long enough (<30cm) to prevent self-heating of the sensor. On the screenshot of the PCB above, the bottom pin is GND (blue), the middle one is Data (yellow) and the top pin is VDD (red). You can find the pin numbering of the sensor here.
