The MPU9250 integrates an accelerometer, a gyroscope, and a magnetometer into a single small package. The reason it is so small is that it uses Micro Electro Mechanical Systems (MEMS) – small mechanical components are made directly on the silicon die and are integrated with the electronic components to make a functional sensor.
 
The module has a built-in LDO regulator, which supplied the MPU9250 with the 3.3V it needs. The LDO cannot handle very high voltages, and it is best powered with 5V. The module also has integrated pullup resistors for the I2C lines.
 
Header pins are provided to break out all the important pins of the IC so it can easily be connected to a breadboard. Mounting holes are provided to facilitate integration into a project.
