What is it?

The I3G4250D is a inertial sensor unit cosit a 3 axis digital gyroscope.

Sensor has user-selectable full scales of ±245/±500/±2000 dps angular rate speed. It is capable of output acceleration data with the 105/208/420/840 Hz rates.

The device may be configured to generate event signals using independent Data Ready/FIFO/Programmable interrupt events.

The interrupt signals can be connected to the transistor driving LED. The interrupt signal INT1 is default connected to the on-board LED. Both INT1 and INT2 are connected to the MOLEX connector.

The I3G4250D has an integrated FIFO buffer allowing the user to store data in order to limit intervention by the host processor.
