The Adafruit MCP9600 I2C Thermocouple Amplifier handles all the analogue complexity of thermocouple measurement for you. Simply connect your thermocouple, wire up I2C, and read accurate temperature data from virtually any thermocouple type — K, J, T, N, S, E, B, and R types are all supported.
The MCP9600 includes built-in cold-junction compensation, configurable temperature alerts, and reports both the thermocouple (hot) and chip (cold) temperatures over I2C. The breakout board features a 3.3V regulator and level shifting, so it works with both 3.3V and 5V logic.

Jargon buster
Plain-language definitions for the technical terms used above.
- 3.3V regulator
- A 3.3V regulator is a power circuit that provides a steady 3.3 volts for parts that need that supply voltage. On a breakout board, it can let the sensor run safely even when the connected microcontroller or power source uses a higher voltage.
- breakout
- A breakout board carries a small or fine-pitched component and brings its connections out to standard, breadboard- and header-friendly pins. Describing a part as a breakout means it can be wired into a project without soldering directly to the component's tiny contacts.
- Cold-junction compensation
- Cold-junction compensation corrects for the temperature at the point where a thermocouple connects to the electronics. It matters because thermocouples measure temperature differences, so this correction is needed for more accurate real-world temperature readings.
- I2C
- I2C is a two-wire communication bus used by many sensors and small modules. It matters because several I2C devices can share the same two wires, but each device needs a compatible address and your controller must support I2C.
- K-Type
- K-Type refers to a common thermocouple probe type made from specific metal alloys and suited to very high temperature measurement. It matters because the amplifier and the probe type must match; a K-Type amplifier is intended for K-Type thermocouples, not every thermocouple style.
- Terminal block
- A terminal block is a connector that joins wires together in a neat, removable, or serviceable way, usually clamping each wire under a screw or spring instead of soldering. It makes it easier to connect, change, or service wiring without permanent joints.
- Thermocouple
- A temperature sensor made from two different metals that produces a very small voltage depending on temperature. Because the signal is tiny, it usually needs careful amplification and accurate measurement hardware.
