The Adafruit MCP9601 (MCP96L01) I2C Thermocouple Amplifier handles all the analogue complexity of thermocouple measurement over a simple I2C interface. Connect your thermocouple, wire up I2C (or use the solderless STEMMA QT connector), and read accurate temperature data from K, J, T, N, S, E, B, and R type thermocouples.

The MCP96L01 chip includes built-in cold-junction compensation, configurable over/under temperature alerts, and reports both the thermocouple (hot) and ambient chip (cold) temperatures. The breakout board features a 3.3V regulator and level shifting, so it works seamlessly with both 3.3V and 5V logic.

Key Features
