Thermocouple Amplifier with 1-Wire Breakout Board - MAX31850K _RPI_USB_KEYB This breakout board has theThermocouples are very sensitive, requiring a good amplifier with a cold compensation reference. So far we've carried the very nice MAX31855 which is an SPI interface thermocouple amplifier. The '855 is great but if you have a lot of thermocouples to measure it isn't terribly easy to use. That's why we are also carrying the new '850 model from Maxim it's a "1 Wire" thermocouple amp which can have any number of breakouts on a single shared I O line.
