Accurate Angles

The Kalman filter really smooths out the noise. Great for attitude estimation without needing a separate gyro module for basic tasks.

Solid Performance

Used this for a balancing robot project and the readings are very stable. The Kalman filter makes a noticeable difference compared to raw accelerometer data.
