3.2 100K NTC or PT1000 Settings
1. Version without 31865: No need to plug a jumper cap when using a 100K NTC
thermistor, and TH0's pull-up resistor value is 4.7K. When using PT1000, you
need to use the jumper cap to short the two pins, as shown below picture. At this
time, TH0's pull-up resistor value is 2.2K (Notice: the temperature accuracy that's
read out this way will be less accurate than that of MAX31865).
2. Version with 31865: Select PT100/PT1000 by DIP switch, two-line or four-wire:
