9DoF Sensor Stick Hookup Guide

Installing the Arduino Library
We've written a full-featured Arduino library to help make interfacing with the LSM9DS1's gyro, accelerometer, and magnetometer as easy-as-possible. Visit the GitHub repository to download the most recent version of the library, or click the link below:
For help installing the library, check out our How To Install An Arduino Library tutorial. You need to move the SparkFun_LSM9DS1_Arduino_Library folder into a libraries folder within your Arduino sketchbook or use the Library Manger to install.
The LSM9DS1_Basic_I2C Example
To verify that your hookup works, load up the LSM9DS1_Basic_I2C example by going to File > Examples > LSM9DS1 Breakout > LSM9DS1_Basic_I2C.
The default values set by this sketch should work for a fresh, out-of-the-box 9DoF Sensor Stick -- it assumes both of the address jumpers haven't been modified. Upload the sketch, then open up your serial monitor, setting the baud rate to 115200. You should see something like this:
The current reading from each axis on each sensor is printed out, then those values are used to estimate the sensor's orientation. Pitch is the angle rotated around the y-axis, roll is the board's rotation around the x-axis, and heading (i.e. yaw) is the sensor's rotation around the z-axis. Try rotating the board (without pulling out any wires!) to see how the values change.
