ITG-3205 is a newer version of InvenSense's ITG-3200  triple-axis digital output gyroscopechips.

The ITG-3205 features three 16-bit analog-to-digital converters (ADCs) for digitizing the gyro outputs, a user-selectable internal low-pass filter bandwidth, and a Fast-Mode I2C (400kHz) interface. Additional features include an embedded temperature sensor and a 2% accurate internal oscillator.

The ITG-3205 can be powered at anywhere between 2.1 and 3.6V. For power supply flexibility, the ITG-3205 has a separate VLOGIC reference pin (labeled VIO), in addition to its analog supply pin (VDD) which sets the logic levels of its serial interface. The VLOGIC voltage may be anywhere from 1.71V min to VDD max. For general use, VLOGIC can be tied to VCC. The normal operating current of the sensor is just 6.5mA.

Communication with the ITG-3205 is achieved over a two-wire (I2C) interface. 

 We are sending the board with pupulated pull-up resistors as shown in the images. If you have more than one I2C sensor with pull up resistors, you can remove these resistors.
