We've carried various MAXIM thermocouple amplifiers and they're great - but thermocouples don't have the best accuracy or precision,
for when the readings must be as good as can be. The MAX31865 handles all of your RTD needs, and can even compensate 3 or 4 wire RTDs
for better accuracy. Connect to it with any microcontroller over SPI and read out the resistance ratio from the internal ADC.
We put a 430? 0.1% resistor as a reference resistor on the breakout. We have some example code that will calculate the temperature
based on the resistance for you.
