L3GD20H is a motion MEMS sensor that sense angular rates on three selectable full scales up to 2000 degree per seconds. With its fast turn-on capability and low power consumption when device is in power down mode, new opportunities are offered to innovative applications such as wearable electronics and activity tracking.

Compared to the previous generation, it has lower power consumption with sleep and power-down modes available that perfectly fit with battery powered application where energy saving is a critical parameter. Its high accuracy and low noise make the L3GD20H an ideal gyroscope to reach portable devices and internet of things applications that are going to increase exponentially in the next coming years.
