Key Features

• Works with any K type thermocouple
• Will not work with any other kind of thermocouple other than K type
• -270degC to +1370degC output in 0.25 degree increments
• 3.3 to 5v power supply. Data line is 3V only
• 1-Wire interface allows any number of thermocouple amps on a single data line

The MAX31850K does everything for you, and can be easily interfaced with any microcontroller that has 1-Wire support. This breakout board has the chip itself, a 3.3V regulator with 10uF bypass capacitors all assembled and tested. This board can be used with 'parasitic power' - where the power is on the data line - or with 'local power' where the power for the converter comes in on the Vin Pin. The MAX31850K data format is very similar to that of the well known 1-Wire DS18B20 temp sensor but it is not drop in compatible without code changes to check for the new '1 Wire family' type. 

Comes with a 2 pin terminal block (for connecting to the thermocouple), 4.7K data line pullup resistor, and pin header (to plug into any breadboard or perfboard). Goes great with Adafruit's 1m K-type thermocouple. Not for use with any other kind of thermocouple, K type only!
