Thermocouples are very sensitive, requiring a good amplifier with a cold-compensation reference. The MAX31855K does everything for you, and can be easily interfaced with any microcontroller, even one without an analog input. This breakout board has the chip itself, a 3.3V regulator with 10uF bypass capacitors and level shifting circuitry, all assembled and tested. Comes with a 2 pin terminal block (for connecting to the thermocouple) and pin header (to plug into any breadboard or perfboard).


  • Works with any K-type thermocouple (do not use with non-K type)
  • -200°C to +1350°C (0.25°C increments)
  • 3.3V/5V
  • SPI output requires 3 digital I/O pins
