Triple Axis Gyro Breakout ITG-3200 Retail
Replacement: None. We are no longer carrying this retail kit in our catalog but we are still carrying our non-retail version here. This page is for reference only.
This is a breakout board for InvenSense's ITG-3200, a groundbreaking triple-axis, digital output MEMS gyroscope in retail packaging. 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. 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-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; the board is shipped with this jumper tied to VCC. 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.
This breakout board is shipped as shown in the images. Note that there are two unpopulated resistors on the I2C lines, these can be added later by the customer (that's you!) if desired.

Triple Axis Gyro Breakout ITG-3200 Retail Product Help and Resources
Core Skill: Soldering
This skill defines how difficult the soldering is on a particular product. It might be a couple simple solder joints, or require special reflow tools.
Skill Level: Noob - Some basic soldering is required, but it is limited to a just a few pins, basic through-hole soldering, and couple (if any) polarized components. A basic soldering iron is all you should need.
See all skill levels
Core Skill: Programming
If a board needs code or communicates somehow, you're going to need to know how to program or interface with it. The programming skill is all about communication and code.
Skill Level: Competent - The toolchain for programming is a bit more complex and will examples may not be explicitly provided for you. You will be required to have a fundamental knowledge of programming and be required to provide your own code. You may need to modify existing libraries or code to work with your specific hardware. Sensor and hardware interfaces will be SPI or I2C.

Core Skill: Electrical Prototyping
If it requires power, you need to know how much, what all the pins do, and how to hook it up. You may need to reference datasheets, schematics, and know the ins and outs of electronics.
Skill Level: Noob - You don't need to reference a datasheet, but you will need to know basic power requirements.

The quickstart (http://www.sparkfun.com/tutorials/265) guide notes that the values provided are not in degrees per second. How can I translate to degrees (or radian) per second?
Such a huge amount of waste plastic for such a small part. How do you sleep at night?
At the very least, you should make the plastic cases easily reusable as enclosures or something.
They also prevent theft.
I don't think the retail products were intended for sale over the web. (Although you can still buy them if you want.)
They were intended to be sold in a brick and mortar store where the packaging needs to be big enough to be hung on a hook and visible to customers. This is a great way of introducing people to electronics! After using the retail stuff to get started, people can then start ordering over the web.
As far as the plastic goes, as long as it's marked, I usually toss it in the recycling bin.
