We will be using this temperature sensor
If you use a DS18B20 sensors, it requires a pullup resistor on the data line. You can connect the sensor data line to pin D10 and then just close the solder jumper SJ12 on the back of the Mayfly to enable the builti-in pullup resistor for that data pin. This saves you from having to add a separate resistor somewhere on the board to pullup D10.
