Introduction

The LSM9DS1 is a versatile, motion-sensing system-in-a-chip. It houses a 3-axis accelerometer, 3-axis gyroscope, and 3-axis magnetometer -- nine degrees of freedom (9DOF) in a single IC! Each sensor in the LSM9DS1 supports a wide range of...ranges: the accelerometer's scale can be set to ± 2, 4, 8, or 16 g, the gyroscope supports ± 245, 500, and 2000 °/s, and the magnetometer has full-scale ranges of ± 2, 4, 12, or 16 gauss. The IMU-in-a-chip is so cool we put it on a quarter-sized breakout board.

The LSM9DS1 is equipped with a digital interface, but even that is flexible: it supports both I2C and SPI, so you'll be hard-pressed to find a microcontroller it doesn't work with.

Covered In This Tutorial

This tutorial is devoted to all things LSM9DS1. We'll introduce you to the chip itself, then the breakout board. Then we'll switch over to example code, and show you how to interface with the board using an Arduino and our LSM9DS1 Arduino library.

The tutorial is split into the following pages:

Required Materials

This tutorial explains how to use the LSM9DS1 Breakout Board with an Arduino. To follow along, you'll need the following materials:

Example hookup

The LSM9DS1 is a 3.3V device! Supplying voltages greater than ~3.6V can permanently damage the IC. As long as your Arduino has a 3.3V supply output, and you're OK with using I2C, you shouldn't need any extra level shifting. But if you want to use SPI, you may need a level shifter.

A logic level shifter is required for any 5V-operating Arduino (UNO, RedBoard, Leonardo, etc). If you use a 3.3V-based 'duino -- like the Arduino Pro 3.3V or 3.3V Pro Mini -- there is no need for level shifting.
