Measgure angular speed (angular movement) with the L3GD20 gyroscop

The L3GD20 from ST Microelectronics is a low-power 3 axis angular rate sensor using the MEMS technology. This sensor expose an I2C interface.

The board expose breakout connexions and an UEXT connector for easier connection on host board (having UEXT connector).

This sensor should be put in the IMU family as it measure the rotation speed in degrees-per-second (dps). It can be used to detect spatial rotation of an object. By example, it can detect a fly rotating on himself to get down toward the ground. Once the rotation done and fly still descending to the ground, the sensor returns NO degrees-per-second change (since the fly is not rotating anymore).
