Tips

When selecting your SBG sensor, note that the Gyroscopes and Accelerometer option should be G4A2.

SBG miniature sensors enclosures are rated IP68, it means they are resistant to dust and water. If the sensor will encounter salt water, we recommend to build your own protection.

The SBG iron calibration tool compensates soft and hard iron effects using a powerful calibration algorithm. We recommend to perform the calibration in real conditions to obtain the best performance.
