The LSM9DS1 is a system-in-package featuring a 3D accelerometer, a 3D gyroscope and a 3D magnetometer, with a linear acceleration full scale of ±2g/±4g/±8/±16 g, a magnetic field full scale of ±4/±8/±12/±16 gauss and an angular rate of ±245/±500/±2000 dps.

It includes a I2C serial bus interface supporting standard and fast mode (100 kHz and 400 kHz) and an SPI serial standard interface. Magnetic, accelerometer and gyroscope sensing can be enabled or set in power-down mode separately for smart power management.

The board is equipped with two Qwiic compatible connectors (JST SM04B-SRSS-TB), this makes it compatible and daisy-chainable with the SparkFun's sensors and with the Adafruit Stemma QT sensors (for 3.3V use only).

This breakout board is compatible only with 3.3V, both power and logic. DO NOT connect it directly to 5V boards.

We developed two libraries, in Python 3 for the Raspberry Pi and in C++ for the Arduino IDE (available for download directly on the Arduino IDE Library Manager or manually on our GitHub page).  Both the libraries support communication over I2C, SPI and the use of the interrupts on pins INT1 and INTM.
Check out schematics and datasheet for more technical specs.

On GitHub you'll find quick instructions to connect the sensor and test the software, for both Raspberry Pi and Arduino.
