This breakout board is based around the latest gyro technology, the L3GD20H from STMicro. It's the upgrade to the L3G4200 with three full axes of sensing. The chip can be set to 250, 500, or 2000 degree-per-second scale for a large range of sensitivity. There's also built in high and low pass sensing to make data processing easier. The chip supports both I2C and SPI so you can interface with any microcontroller easily.
