The Adafruit ICM-20649 breakout features a wide-range 6-DoF IMU capable of measuring up to ±30g acceleration and ±4000°/s gyroscope rotation — roughly double the range of standard IMUs. When typical ±16g accelerometers and ±2000°/s gyros aren't enough, this sensor delivers the extended measurement range needed for high-impact and fast-rotation applications.
Mounted on a breadboard-friendly breakout with onboard voltage regulation and level shifting, this board works with both 3.3V and 5V logic. STEMMA QT / Qwiic connectors provide solderless I2C hookup, and Adafruit provides ready-to-use Arduino and Python libraries.
Key Features
- ±30g Accelerometer – Wide-range 3-axis acceleration measurement for high-impact applications
- ±4000°/s Gyroscope – Extended 3-axis angular rate sensing for fast rotations
- 6 Degrees of Freedom – Combined accelerometer and gyroscope in a single sensor
- STEMMA QT / Qwiic Connectors – Solderless I2C connection with daisy-chain support
- 3.3V & 5V Compatible – Onboard voltage regulator and level shifting for broad compatibility
- I2C Interface – Simple two-wire data connection plus power
- Breadboard-Friendly – Standard breakout board format with 0.1" header pitch
Ideal For
- Sports analytics — golf swings, soccer kicks, and high-impact motion tracking
- Motorsport and racing telemetry requiring extended G-force measurement
- Robotics and drone applications with fast rotational movements
- Any project where standard ±16g / ±2000°/s IMU ranges are insufficient
Package Contents
- 1× Adafruit ICM-20649 Wide Range 6-DoF IMU Breakout

Jargon buster
Plain-language definitions for the technical terms used above.
- 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.
- Gyroscope
- A gyroscope measures rotation, such as how fast a board is turning around its X, Y, and Z axes. This matters for projects like gesture controls, balancing robots, and motion tracking where tilt or rotation changes need to be detected.
- 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.
- IMU
- An IMU (Inertial Measurement Unit) combines motion sensors, typically an accelerometer and gyroscope and sometimes a magnetometer, to measure movement and orientation. It can sense motion, tilt, vibration, rotation, and changes in direction, which is useful for tasks such as navigation, stabilisation, gesture detection, and asset tracking.
- Qwiic
- Qwiic is a plug-in connector system for I2C devices that uses small 4-pin cables, so you can connect compatible sensors without soldering. It matters because your controller or adapter also needs Qwiic, or you will need a cable or breakout to wire it up.
- STEMMA
- A plug-and-cable connection system used on some maker electronics boards to make wiring simpler. If a product uses STEMMA, you need the matching cable or connector type to plug it in without soldering.
- STEMMA QT
- A small plug-in connector system for I2C boards that lets you connect compatible sensors and controllers without soldering. It matters because it can make wiring faster and less error-prone, especially when adding several small modules to a project.
