Introduction
The MCP9808 is a digital temperature sensor that is mounted on the PCB to measure the ambient temperature. More information can be found on the manufacturers page here. Adafruit also has a good tutorial on how to use this sensor here. It uses I2C for communication and shares the bus with the FT5206 but has a different address of 0x1F.
