Introduction

Grove - 3-Axis Digital Gyro module based on ITG 3200. It is the world’s first single-chip, digital-output, 3-axis MEMS motion processing gyro optimised for gaming, 3D mice, and motion-based remote control applications for Internet connected Digital TVs and Set Top Boxes. The ITG-3200 features three 16-bit analog-to-digital converters (ADCs) for digitising the gyro outputs, a user-selectable internal low-pass filter bandwidth, and a Fast-Mode I2C (400kHz) interface.

Features

Supply Voltage: 3.3V, 5V Operation Current: 6.5mA Standby current: 5μA Sensitivity: 14 LSBs per °/sec Full scale range: ±2000°/sec Acceleration: 10,000g for 0.3ms I2C Interface ±2000°/s full scale range and 14.375 LSBs per °/s sensitivity Three integrated 16-bit ADCs On-chip temperature sensor Integrated amplifiers and low-pass filters Hermetically sealed for temp and humidity resistance RoHS and Green compliant Demonstration

This demo will show you how to get data from this digital gyro, the data is in the unit of rad/s. Here we need a Grove - 3-Axis Digital Gyro and a Seeeduino V3.0. Hardware Installation Hardware installation is very easy, because there's an I2C Grove in Seeeduino, so what we need to to is connect it to I2C Grove via a Grove cable.
