The board includes an LSM6DSOX, a 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. This new sensor from ST has very low gyro zero rate and noise, compared to the MPU6050 or even LSM6DS33 so it's excellent for orientation fusion usage: you'll get less drift and faster responses.
The LSM6DSOX has flexible data rates and ranges. For the accelerometer: ±2/±4/±8/±16 g at 1.6 Hz to 6.7KHz update rate. For the gyroscope: ±125/±250/±500/±1000/±2000 dps at 12.5 Hz to 6.7 KHz. There's also some nice extras, such as built in tap detection, activity detection, pedometer/step counter and a programmable finite state machine / machine learning core that can perform some basic gesture recognition.
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. Check out our guide on how to do that!
To make getting started fast and easy, we placed the sensors 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, we expose only the I2C interface and some interrupt pins from each chip. 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.
