I read somewhere that is what you do to find the angular position roughly... I may be wrong.</p>

I divide by 16.384 since the sensor's output data is of 16 bits, 2^15 = 32768 (considering negative and positive values) and then you have to multiply by the sensitivity which is 2000 and it gives me: 32768/2000 = 16.384. But when I integrate the gyroscope values to get the angles I get a 10 degree offset over a 90 degree turn so I compensate this by multiplying the sensor value by 1.125 (90/80) and dividing by 16.384, so the final calculation I do is sensorValue/14.564</p>

My best guess would be to take read(X, Y, Z) and divide it by 14.375. It would be really helpful to see how its done properly though.</p>

I have some questions here.<p>Is it necessary or a must to connect the CLKIN to GND if it is unused? Also, do I have to connect AD0 to GND too? Lastly, can I use a pull-up resistor(1K resistor) instead of using a logic level converter to make sure the power input for ITG 3200 is always 3.3V?</p><p>Thanks!</p></p>

It does have those pins, except they are in the middle of the board.</p>

It's been redesigned to add mounting holes and be in line with the other boards in the <a href="https://www.sparkfun.com/products/12056" rel="nofollow">Sensor Kit</a><p>Edit: oh, and an extra resistor for the address selection jumper.</p></p>
