Gyroscope Module 3-Axis L3G4200D with Propeller

Does this gyro output a 3.3 volt signal or a 5 volt signal? I cannot find in the documentation, and I need to know so I can use a resistor or not. I know the gyro regulates itself down to 2.5 volt so could it also use this for its output?

    Did you try to Google "L3G4200D datasheet" ?

    I found: http://www.pololu.com/file/download/L3G4200D.pdf?file_id=0J491

    Excerpt: "Wide supply voltage: 2.4 V to 3.6 V"

    It's a 3.3V device.

    While the chip itself is a 3.3 volt device, the module includes built in level shifting circuitry to enable its use with other devices. The documentation and other information is located on the product's Parallax store web page. Look toward the bottom, under where its says "Made in USA".

    Try it with the series resistors (1K or less since I2C should have 10K pullups) because they usually dont matter if present. Most likely the output is 3V3 (same as the supply voltage) without looking at the specs.

    It looks like everything is already built in... The module "is designed for use with a large variety of microcontrollers with different voltage requirements".

    The Parallax KickStart page has diagrams showing how to connect the gyroscope module to a Basic Stamp Homework Board, a Propeller QuckStart and an Arduino Uno, along with demo code. All they use is some wire.
