9DoF Sensor Stick

The SparkFun 9DoF Sensor Stick is an easy-to-use 9 Degrees of Freedom IMU. The Sensor Stick deftly utilizes the LSM9DS1 motion-sensing system-in-a-chip, the same IC used in the [SparkFun 9DoF IMU Breakout](https://www.sparkfun.com/products/13284). It houses a 3-axis accelerometer, 3-axis gyroscope, and 3-axis magnetometer “ nine degrees of freedom (9DoF) in a single IC!

The onboard LSM9DS1 from STMicroelectronics is equipped with a digital interface, but even that is flexible. The biggest difference between the two boards, besides the slimmed down 0.9"x0.4" footprint, is the number of broken-out pins, with the Sensor Stick featuring only four for quick setup and ease of use.

The LSM9DS1 is one of only a handful of ICs that can measure three key properties of movement “ angular velocity, acceleration and heading “ in a single IC. By measuring these three properties, you can gain a great deal of knowledge about an objects movement and orientation. The LSM9DS1 measures each of these movement properties in three dimensions. That means it produces nine pieces of data: acceleration in x/y/z, angular rotation in x/y/z, and magnetic force in x/y/z.

Each sensor in the LSM9DS1 supports a wide spectrum of ranges: the accelerometers scale can be set to ± 2, 4, 8, or 16g, the gyroscope supports ± 245, 500, and 2000°/s, and the magnetometer has full-scale ranges of ± 4, 8, 12, or 16 gauss.
