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 optimized 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 digitizing the gyro outputs, a user-selectable internal low-pass filter bandwidth, and a Fast-Mode I2C (400kHz) interface.


Model:SEN11763P




Features

  • Supply Voltage: 3.3V, 5V
  • Operation Current: 6.5mA
  • Standby current: 5μA

  • 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 instration 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.
