It communicates over standard I2C and runs on 2.7V to 5.5V power and logic, making it compatible with virtually any microcontroller or single-board computer.\n\nWith three address jumpers on the back of the breakout, you can connect up to 8 sensors on a single I2C bus without address collisions. The STEMMA QT / Qwiic connectors on both sides allow solderless daisy-chaining for quick prototyping.\n\nKey Features\n\n\nHigh Accuracy – ±0.25°C typical (±0.5°C max from −20°C to +100°C)\n\nFine Resolution – 0.0625°C measurement steps\n\nWide Operating Range – −40°C to +125°C\n\nI2C Interface – Simple two-wire digital communication\n\nUp to 8 on One Bus – Three configurable address jumpers\n\nWide Voltage Range – 2.7V to 5.5V power and logic\n\nLow Power – 200 µA typical operating current\n\nSTEMMA QT / Qwiic Ports – Solderless I2C connections on both sides\n\n\nIdeal For\n\nPrecision environmental monitoring and data logging\nMulti-point temperature measurement arrays\nCalibration and reference temperature applications\nIoT and weather station projects\n\n\nPackage Contents\n\n1× Adafruit MCP9808 Temperature Sensor breakout (with STEMMA QT / Qwiic connectors)\n1× Header pin strip\n\n\n\nNote: STEMMA QT cable not included. Some soldering is required to attach the header strip for breadboard use.\n\n\nResources\n\nMCP9808 Guide with Arduino & CircuitPython (Adafruit Learn)\nWhat is STEMMA QT?
