SparkFun: IMU Breakout - MPU9250

The SparkFun MPU-9250 IMU Breakout features the latest 9-axis MEMS sensor from InvenSense. Each of these 9DoF breakouts feature an MPU-9250 with a System in Package (SiP) that combines two chips: the MPU-6500, which contains a 3-axis gyroscope as well as a 3-axis accelerometer, and the AK8963, which features a 3-axis magnetometer. This breakout has been designed to be smaller than other offerings to fit in smaller projects. However, if you plan to use a breadboard, or secure the IMU board to a project with something like epoxy, the mounting holes can be easily snapped off. To achieve its smaller size, the MPU-9250 Breakout features PTH pins that have been wrapped around the border of the PCB in three rows of three or four. The top rowis all one needs to get the most functionality out of the IMU. These include the I2C and power interface. The second most likely to be used set of PTHs are found along the bottom. This includes the address pin, the interrupt pin, and the IO voltage supply
