3 Axis Digital-Output Gyro Sensor (ITG-3200)
This is a breakout board for InvenSense's ITG-3200, a groundbreaking triple-axis, digital output MEMS gyroscope sensor. 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.
Additional features include an embedded temperature sensor and a 2% accurate internal oscillator.
The ITG-3200 can be powered at anywhere between 2.1 and 3.6V. For power supply flexibility, the ITG-3200 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.
Communication with the ITG-3200 is achieved over a two-wire (I2C) interface. The sensor also features a interrupt output, and an optional clock input.
A jumper on the top of the board allows you to easily select the I2C address, by pulling the AD0 pin to either VCC or GND. If you don't plan on using the CLKIN pin, you can short the jumper on the bottom of the board to tie it to GND.
Note that there are two unpopulated resistors on the I2C lines
- Digital-output X-, Y-, and Z-Axis angular rate sensors (gyros) on one integrated circuit
- Digitally-programmable low-pass filter
- Low 6.5mA operating current consumption for long battery life
- Wide VDD supply voltage range of 2.1V to 3.6V
- 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
