This is the SparkFun Photon IMU Shield, a versatile motion-sensing add-on board for your Photon device. Each IMU shield is equipped with an on-board LSM9DS1 system-in-a-chip that houses a 3-axis accelerometer, 3-axis gyroscope, and 3-axis magnetometer. That's right, 9 degrees of freedom（9DOF）from a single IC！
Each sensor in the LSM9DS1 from STMicroelectronics supports a large variety of ranges：the accelerometer's scale can be set to ± 2, 4, 6, 8, or 16 g, the gyroscope supports ± 245, 500, and 2000 °/s, and the magnetometer has full-scale ranges of ± 2, 4, 8, or 12 gauss. The SparkFun Photon IMU Shield comes with the headers already soldered on, so you can plug and play！
The Particle Photon is a tiny WiFi development kit for creating connected projects and products. Sporting a 120Mhz ARM Cortex M3 and built-in WiFi, the Photon is not only powerful, but easy to use. The small form factor is ideal for IoT projects with cloud-connectivity.
Note：
Not only can this shield operate with the Photon, it can also be used with the Particle Core！ We understand that there are a ton of you out there who still haven't been able to get your hands on a Photon yet and would like to start playing with this shield now. If that person is you we hope we have obliged！
