Connecting a LSM9DS0 9DoF module to Arduino Uno I got a bit confused by Sparkfun's hookup guide for this 9DoF breakout module.

It says the VDD-in on the breakout "should [get voltage] regulated between 2.4V and 3.6V", yet in their example they do not hook it up to the Arduino's 3.3V pin, but instead they use the 5V and a bi-directional logic level converter.

Do I need to use the logic level converter, or can I just hook the module up to the 3.3V pin of my Arduino Uno without damaging the breakout module?
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.
