Hardware Connections

The MPU-9250 breakout board runs on 3.3 VDC, so a 3.3V USB to UART bridge such as the SparkFun FTDI Basic Breakout - 3.3V or the SparkFun Beefy 3 - FTDI Basic Breakout can be used to power and bridge communication with a micro controller. In this case an Arduino Pro Mini 328 - 3.3V/8MHz was chosen so logic level translation isn't needed.

Only 4 connections are needed for I2C communication.

For stability in the breadboard, another four pins were soldered on: VDDIO, AD0/SDO, CS, and INT.
