* 13 : 100k Hisens 3950 1% up to 300°C for hotend "Simple ONE " & "Hotend "All In ONE"
* 15 : 100k thermistor calibration for JGAurora A5 hotend
* 18 : ATC Semitec 204GT-2 (4.7k pullup) Dagoma.Fr - MKS_Base_DKU001327
* 20 : Pt100 with circuit in the Ultimainboard V2.x with mainboard ADC reference voltage = INA826 amplifier-board supply voltage (notes: 1) Must use an ADC input without a pull up resistor. 2) Some INA826 amplifiers do not operate properly at 3.3V. In this case consider using thermal tables 147 [PT100, 4.7K pullup, no amplifier], 110 [PT100, 1K pullup, no amplifier], or 21 [PT100, no pullup, 5V powered amplifier])
* 21 : Pt100 with circuit in the Ultimainboard V2.x with 3.3v ADC reference voltage (STM32, LPC176x....) and 5V INA826 amplifier board supply. (note: ADC pins are not 5V tolerant. Not recomended as there is a small chance of damaging the CPU by going beyond 500°C.)
* 20 : Pt100 with circuit in the Ultimainboard V2.x with mainboard ADC reference voltage = INA826 amplifier-board supply voltage. NOTES: 1. Must use an ADC input without a pullup resistor. 2. Some INA826 amplifiers are unreliable at 3.3V so consider using sensor 147, 110, or 21.
* 21 : Pt100 with circuit in the Ultimainboard V2.x with 3.3v ADC reference voltage (STM32, LPC176x....) and 5V INA826 amplifier board supply. NOTE: ADC pins are not 5V tolerant. Not recommended because it's possible to damage the CPU by going over 500°C.
* 22 : 100k (hotend) with 4.7k pullup to 3.3V and 220R to analog input (as in GTM32 Pro vB)
* 23 : 100k (bed) with 4.7k pullup to 3.3v and 220R to analog input (as in GTM32 Pro vB)
* 201 : Pt100 with circuit in Overlord, similar to Ultimainboard V2.x
