The navX2-Micro circuit board and official firmware provide inertial and magnetic measurements, with a range, accuracy and update rate as described on this page.
Note that certain performance specifications are only valid after a start-up Gyroscope/Accelerometer Calibration period, during which time the navX2-Micro circuit board must be held still.
Additional details can be found in the navX2-Micro datasheet.
