## Description

Thermocouples are very sensitive, requiring a good amplifier with a cold-compensation reference, as well as calculations to handle any non-linearities. For a long time Adafruit have [suggested Adafruit's MAX31855K breakout, which works great but is only for K-type thermocouples](https://core-electronics.com.au/thermocouple-amplifier-max31855-breakout-board-max6675-upgrade-v2-0.html). Now Adafruit are happy to offer a great new thermocouple amplifier/converter that can handle just about *any* type of thermocouple, and even has the ability to give you notification when the temperature goes out of range, or a fault occurs. Very fancy!

This converter communicates over 4-wire SPI and can interface with any **K**, **J**, **N**, **R**, **S**, **T**, **E**, or **B** type thermocouple.

This breakout 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 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). Adafruit even added inline resistors and a filter capacitor on-board for better stability, as recommended by Maxim. [Goes great with Adafruit's 1m K-type thermocouple](https://core-electronics.com.au/thermocouple-type-k-glass-braid-insulated-k.html) or any other thermocouple, really!

- Works with any **K**, **J**, **N**, **R**, **S**, **T**, **E**, or **B** type thermocouple
- **-210°C to +1800°C output in 0.0078125° resolution** - note that many thermocouples have about ±2°C to ±6°C accuracy or worse depending on the temperature and type, so the resolution will be a lot better than the accuracy!
- Internal temperature reading
- 3.3 to 5v power supply and logic level compliant!
- SPI data requires any 4 digital I/O pins

**Please note: this does not include a thermocouple!**
