Add motion and orientation sensing to your project with this compact 6 Degree of Freedom IMU breakout built around the ST LSM6DS3TR-C. It combines a 3-axis accelerometer for measuring gravity and acceleration with a 3-axis gyroscope for measuring spin and twist.
The breakout includes voltage regulation and level-shifted inputs, so it can be used with 3V or 5V power and logic. It supports both I2C and SPI, comes fully assembled and tested, includes extra header for breadboard use, and has four mounting holes for secure installation.
For quick I2C wiring, the board includes SparkFun qwiic-compatible STEMMA QT connectors, so you can connect with a plug-and-play cable instead of soldering. The I2C address can be changed using the solder jumper on the back, allowing two of these sensor boards on the same bus.
Adafruit provides Arduino/C++ and Python/CircuitPython library support for getting accel/gyro data into your project. This chip is similar to the discontinued LSM6DS33, but it is not firmware-compatible with the LSM6DS33, so code must be recompiled and configured for the exact chip.

This breakout does not include a magnetometer, which is often required for accurate orientation; it can be paired with a compatible 3-axis magnetometer for full orientation projects.
Jargon buster
Plain-language definitions for the technical terms used above.
- breakout
- A breakout is a small circuit board that makes a tiny or hard-to-solder component easier to connect to with standard pins. It matters because this OLED module can be wired into a microcontroller project without needing to solder directly to the display’s fine contacts.
- CircuitPython
- A beginner-friendly version of Python designed to run directly on microcontroller boards. If a product supports CircuitPython, you can often program it by copying code files onto the board rather than setting up a more complex toolchain.
- Gravity
- Gravity is DFRobot’s plug-in connector system for sensors, motors and modules, using standard cables to reduce loose jumper wiring. It matters because Gravity-compatible parts can connect directly to these ports, while non-Gravity parts may need adapters or manual wiring.
- 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.
- I2C address
- An I2C address is the number a device uses so a microcontroller can tell it apart from other devices on the same I2C bus. It matters because two devices with the same fixed address may conflict if used together.
- IMU
- An Inertial Measurement Unit combines motion sensors to measure movement and orientation. It matters for asset tracking because it can detect movement, tilt, vibration, or changes in direction.
- magnetometer
- A sensor that measures magnetic fields, often used to work out compass direction. It matters because nearby magnets, motors, or metal objects can affect readings and may require calibration.
- 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.
- solder jumper
- A solder jumper is a small pair or group of pads on a circuit board that can be bridged or cut with solder to change a hardware setting. It matters because changing modes may require careful soldering rather than just changing software.
- SPI
- A fast serial communication bus often used for displays, memory cards, and sensors. It matters because SPI devices need specific pins for clock and data, plus a separate chip-select line for each device.
- 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.
