Adafruit LSM6DS3TR-C + LIS3MDL - Precision 9 DoF IMU - STEMMA QT / Qwiic

Enhance your Arduino project with precise motion, direction, and orientation sensing using this 9 Degrees of Freedom (9-DoF) sensor from ST. This compact breakout board combines two chips to provide full-motion data for your projects, offering high-quality sensing for all your motion-related needs.

Features:

• ST LSM6DS3TR-C (LSM6DS3): This is a 6-DoF IMU (Inertial Measurement Unit) combining a 3-axis accelerometer and a 3-axis gyroscope. The accelerometer measures gravity to determine orientation and acceleration, while the gyroscope measures spin and twist for rotation tracking.
• LIS3MDL 3-Axis Magnetometer: Detects the direction of the strongest magnetic force, typically used to find magnetic north, adding the final piece for full 9-DoF motion and orientation tracking.
• Voltage Regulation and Level Shifting: The board is designed to work with both 3.3V and 5V power/logic devices, making it versatile for various projects.
• I2C Interface: The board communicates through a simple I2C interface, allowing easy two-wire connection plus power and ground.
• STEMMA QT Connectors: Includes SparkFun Qwiic-compatible connectors for easy plug-and-play I2C connections. No soldering required—just wire up using a compatible cable to quickly start collecting 9-DoF data.
• Customizable I2C Addresses: Solder jumpers on the back allow you to set unique I2C addresses, so you can connect two boards on the same I2C bus for more sensors.
• Fully Assembled and Tested: The breakout board is fully assembled and tested, with extra header pins for easy breadboard use. Four mounting holes provide a secure connection for your project.
• Libraries Included: Ready-to-use libraries for Arduino/C++ are available for the accelerometer/gyro and magnetometer. Advanced features like FIFO management and tap detection are supported by ST’s own library.

This board is perfect for anyone needing precise motion sensing, whether you're building a robot, wearable, or any project involving spatial orientation. With easy integration, versatile power options, and I2C communication, you'll have everything you need to get started right away!
