ΣΕΝΣΟΡΑΣ 3 ΑΞΟΝΩΝ ΓΥΡΟΣΚΟΠΙΚΟΣA

The L3GD20 is a low-power three-axis angular rate sensor. It includes a sensing element and an IC interface capable of providing the measured angular rate to the external world through a digital interface. The board made by Olimex has I2C on the UEXT connector for easier connection with host boards.
