Add motion, direction and orientation sensing to your project with this all-in-one 9-DOF sensor that is STEMMA QT ready for easy plug-n-play usage.
Inside the chip are three sensors, one is a classic 3-axis accelerometer, which can tell you which direction is down towards the Earth (by measuring gravity) or how fast the board is accelerating in 3D space. The other is a 3-axis magnetometer that can sense where the strongest magnetic force is coming from, generally used to detect magnetic north. The third is a 3-axis gyroscope that can measure spin and twist. By combining this data you can REALLY orient yourself.
We also stock a larger LSM9DS1 breakout. This version is more petite, and includes SparkFun qwiic compatible STEMMA QT connectors for the I2C bus so you don't even need to solder! Just wire up to your favorite micro like the STM32F405 Feather with a plug-and-play cable to get 9-DoF data ASAP.
Here are the key LSM9DS1 specifications:
- Accelerometer range is ±2/±4/±8/±16 g
- Magnetometer range is ±4/±8/±12/±16 gauss
- Gyroscope range is ±245/±500/±2000 dps ranges.
To make getting started fast and easy, Adafruit 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, they expose both the SPI and 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. Two mounting holes make for a secure connection.
