Add motion, direction and orientation sensing to your project with this compact STEMMA QT version of the LSM9DS1 9-DOF sensor from Adafruit. The LSM9DS1 combines a 3-axis accelerometer, 3-axis magnetometer and 3-axis gyroscope into a single chip for full orientation tracking.
This version features two STEMMA QT / Qwiic connectors for solderless I2C connection — just plug in a compatible cable and start reading sensor data immediately. The board also breaks out SPI and interrupt pins, and includes voltage regulation and level shifting for use with 3.3V or 5V microcontrollers.
Key Features
- 3-Axis Accelerometer – ±2/±4/±8/±16 g selectable ranges
- 3-Axis Magnetometer – ±4/±8/±12/±16 gauss ranges for compass heading
- 3-Axis Gyroscope – ±245/±500/±2000 degrees-per-second ranges
- STEMMA QT / Qwiic Connectors – Solderless I2C connection, plug-and-play
- Dual Interface – I2C (via STEMMA QT or header) and SPI supported
- Wide Voltage Range – 3–5V power and logic with on-board regulator and level shifting
- Compact Design – Smaller than the standard LSM9DS1 breakout, with two mounting holes
Also Available
- LSM9DS1 9-DOF Breakout – Larger breakout with four mounting holes
- LSM9DS0 9-DOF Breakout – Original version with different range options
- L3GD20H + LSM303 9-DOF Breakout – Two-chip design with I2C interface
- BNO055 STEMMA QT – Sensor fusion with absolute orientation output
Ideal For
- Motion and activity tracking projects
- Robot orientation and navigation
- Tilt-compensated compass applications
- Rapid prototyping with solderless connections
Package Contents
- 1× Adafruit LSM9DS1 STEMMA QT Breakout Board (assembled and tested)

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.
- 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.
- 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.
- 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
- 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.
