High current wiring effects
High current in wiring and printed circuit traces can be the cause of errors in magnetic field
measurements for compassing.
Conducto-generated magnetic fields add to earth’s magnetic field, creating errors in
compass heading computation.
Keep currents that are higher than 10 mA a few millimeters further away from the sensor IC.
