3-Axis MEMS Motion SensorsOVERVIEW InvenSense’s 3-axis gyroscopes and 3‑axis accelerometers are suitable for applications where a high-performance angular motion sensor is needed. These sensors support a wide range of applications including Motion UI, Sports, and Image Stabilization. The family includes parts with on‑board FIFO and a secondary I²C interface to support external sensors such as an accelerometer and compass. |
