Adafruit LSM6DS3TR-C + LIS3MDL Precision 9-DoF IMU combines two ST sensors on a single breakout to give you full 9-axis motion sensing in one easy-to-use board. It pairs the LSM6DS3TR-C 6-DoF accelerometer and gyroscope with the LIS3MDL 3-axis magnetometer for orientation, motion, spin, and heading detection.
The accelerometer measures gravity and linear acceleration, the gyroscope tracks rotation and twist, and the magnetometer senses magnetic field direction for compass-style heading data. Together, these three triple-axis sensors provide 9 degrees of freedom for robotics, wearables, balancing projects, motion logging, gesture detection, and embedded navigation experiments.
This breakout is designed for quick integration: it includes onboard voltage regulation, level-shifted inputs for use with 3V or 5V systems, and SparkFun qwiic compatible STEMMA QT connectors for solderless I2C wiring. The board comes fully assembled and tested, includes header strips for breadboard use, and provides mounting holes for secure installation. QT cable is not included.
A practical note for developers: the LSM6DS3TR-C is similar to the older LSM6DS33, but it is not firmware-compatible with that part. If you are updating an existing design, make sure your code is compiled for the exact chip in use.
Technical details for the Adafruit LSM6DS3TR-C + LIS3MDL Precision 9-DoF IMU breakout.

| Mounting | Four mounting holes |
| Assembly | Fully assembled and tested; header included for breadboard use |
Only the I2C interface and some interrupt pins from each sensor are exposed on this breakout, making it straightforward to wire into microcontroller projects with power, ground, SDA, and SCL.
Arduino/C++ libraries are available for both the accel/gyro and the magnetometer, and ST also provides more advanced libraries for features such as FIFO management and tap detection.
This board is a good fit for AHRS and orientation experiments, robotics, handheld motion sensing, activity detection, digital compasses, and embedded projects that need reliable 9-axis motion data without building a multi-board sensor stack.
This breakout combines two ST sensors: the LSM6DS3TR-C for 3-axis accelerometer + 3-axis gyroscope data, and the LIS3MDL for 3-axis magnetometer data. Together they provide 9 degrees of motion and orientation sensing.
Yes. The board includes voltage regulation and level-shifted inputs, so it can be used with both 3V and 5V power/logic devices.
On this breakout, only the I2C interface is exposed, along with some interrupt pins from each chip. It also includes STEMMA QT / SparkFun Qwiic compatible connectors for quick I2C wiring.
Yes. Solder jumpers on the back let you change the I2C addresses, so two of these boards can be used on one I2C bus.
It is very similar to the discontinued LSM6DS33, but it is not firmware-compatible with it. If you are using a supporting library, you need to select the exact chip and recompile your code.
The breakout comes fully assembled and tested, and it includes some extra header for breadboard use. A QT cable is not included.
