Connecting a LSM9DS0 9DoF module to Arduino Uno
I might be missing the part of the hookup guide you're looking at but I can't see it being hooked up to 5V. 

In the "Simple Hardware Hookup (I2C)" section they show two possiblilities a 5V Arduino hooked up via a logic level converter and a 3.3V Arduino hooked up directly. The logic level converter will need a 5V &amp; 3.3V connection from the Arduino, but not the IMU.
