1-Wire Thermocouple is a thermocouple to 1-wire converter board built around Maxim MAX31850 cold-junction compensated 1-Wire thermocouple-to-digital converter chip. The chip works only with 3.3V supply and logic level and there is on-board 3.3V LDO regulator and level converter for compatibility with 5V based 1-Wire networks. Due to the level shifting of the 1-Wire signals the only powering option is via 5V supply i.e. using parasite power is not supported.
