Add motion, direction and orientation sensing to your project with this all-in-one 9-DOF sensor from Adafruit. The LSM9DS1 from ST Micro combines a 3-axis accelerometer, 3-axis magnetometer and 3-axis gyroscope into a single chip — the updated successor to the LSM9DS0.
The breakout board includes a 3V regulator and level-shifting circuitry, so it works with both 3.3V and 5V microcontrollers. Both I2C and SPI interfaces are supported, with library support for each.
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
- Temperature Sensor – On-chip temperature reading
- Dual Interface – I2C and SPI supported
- Wide Voltage Range – 3–5V power and logic with on-board regulator and level shifting
- Breadboard-Friendly – Power and data pins on one side, interrupt pins on the other
- Four Mounting Holes – For secure mechanical attachment
LSM9DS1 vs LSM9DS0
- Accelerometer – LSM9DS1 offers ±2/±4/±8/±16 g (no ±6 g range). LSM9DS0 has ±2/±4/±6/±8/±16 g.
- Magnetometer – LSM9DS1 offers ±4/±8/±12/±16 gauss (higher max range). LSM9DS0 has ±2/±4/±8/±12 gauss (lower minimum).
- Gyroscope – Both share ±245/±500/±2000 dps ranges.
- Accuracy – LSM9DS0 has slightly better zero-rate (±25 vs ±30 dps) and accelerometer offset (±60 vs ±90 mg). These differences may not matter for most projects.
- Price – The LSM9DS1 is generally lower cost than the LSM9DS0.

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.
- Matter
- A smart home connectivity standard designed to let devices work across different ecosystems. It matters if you want a project to integrate more easily with platforms such as Apple Home, Google Home, or other Matter-compatible systems.
- 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.
