4 Mechanical and Electrical Specifications

4.1 General Considerations

Fusion algorithms can be tuned to trade off one performance parameter versus another. Examples

include:

• Speedy handling of magnetic interference versus slower convergence to magnetic north

• Smoothness versus responsiveness

• Accuracy versus bandwidth

NOTE

All of the above means that there is no one correct configuration. Accordingly, this datasheet presents

typical performance as observed on the sample projects supplied by Freescale on specific Freescale

development platforms. No attempt has been made to measure a statistically significant number of

boards. Measured values are typically those observed on as few as one board.
