MAX31855 K-type thermocouple module

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).

Features:

1. Works with any K type thermocouple
2. Will not work with any other kind of thermocouple other than K type
3. -200°C to +1350°C output in 0.25-degree increments – note that K thermocouples have about ±2°C to ±6°C accuracy
4. Internal temperature reading
5. 3.3 to 5v power supply and logic level compliance!
6. SPI data output requires any 3 digital I/O pins.
