This is a breakout board for InvenSense’s ITG-3205. The ITG-3205 is the world’s first single-chip, digital-output, 3-axis MEMS gyro IC optimized for gaming, 3D mice, and 3D remote control applications. 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.

Triple –axis gyroscope breakboard is ideal for:
• Motion-enabled game controllers
• Motion-based portable gaming
• Motion-based 3D mice and 3D remote controls
• “No Touch” UI
• Health and sports monitoring

The ITG-3205 triple-axis MEMS gyroscope includes a wide range of features:
• Digital-output X-, Y-, and Z-Axis angular rate sensors (gyros) on one integrated circuit
• Three integrated 16-bit ADCs provide simultaneous sampling of gyros
application development and making for more-responsive motion processing
• Wide VDD supply voltage range of 2.1V to 3.6V
• Flexible VLOGIC reference voltage allows for I2C interface voltages from 1.71V to VDD
• Standby current: 5µA
• Digital-output temperature sensor
• Fast Mode I2C (400kHz) serial interface
• Optional external clock inputs of 32.768kHz or 19.2MHz to synchronize with system clock
