The 5543-ADA is a high-quality sensor that integrates two powerful chips to create a strong and reliable motion, direction and orientation sensor!
Add high-quality motion, direction, and orientation sensing to your Arduino project with this all-in-one 9 Degree of Freedom (9-DoF) sensor with sensors from ST. This little breakout contains two chips that sit side-by-side to provide 9 degrees of full-motion data.
The board includes an ST LSM6DS3TR-C (a.k.a LSM6DS3), a great entry-level 6-DoF IMU accelerometer + gyro. The 3-axis accelerometer can tell you which direction is down towards the Earth (by measuring gravity) or how fast the board is accelerating in 3D space. The 3-axis gyroscope can measure spin and twist.
It also includes a LIS3MDL 3-axis magnetometer that can sense where the strongest magnetic force is coming from, generally used to detect magnetic north. The three triple-axis sensors add up to 9 degrees of freedom, by combining this data you can orient the board.
The sensors are placed on a compact breakout board with voltage regulation and level-shifted inputs. That way you can use them with 3V or 5V power/logic devices without worry. To make usage simple, only the I2C interface and some interrupt pins from each chip are exposed. The breakout comes fully assembled and tested, with some extra header so you can use it on a breadboard. Four mounting holes make for a secure connection.
Additionally, since it speaks I2C you can easily connect it up with two wires (plus power and ground!). We've even included SparkFun qwiic compatible STEMMA QT connectors for the I2C bus so you don't even need to solder! Just wire up to your favourite micro like the STM32F405 Feather with a plug-and-play cable to get 9 DoF data ASAP. To have two of these sensor boards on one bus, you can change the I2C addresses on the back using the solder jumpers. QT Cable is not included, but we have a variety in the shop.

Here are some libraries to help you get these sensors integrated with your Arduino/C++. This library covers the accel/gyro and this library covers the magnetometer.
For advanced Arduino usage, ST has its own fully-featured library for the LSM6DS3TR-C, which includes extras such as FIFO management and tap detection. They also have a library for the LIS3MDL magnetometer.
