I’ve been asked how to connect a Sparkfun breakout board for the ITG3200 to an Arduino UNO. Here’s a schematics of the connection. If you are using an Arduino Mega you’ll have to use pins 20 (SDA) and 21 (SCL) instead of A4 and A5.
IMPORTANT: Remember that in order to use this setup you have to disable the internal pullups of the ATMEGA. Note that Wire will enable them by default.
