Hi,
I'm using an AK8963C compass chip on a breakout board.
I'm getting errors, that possibly could be caused by inteference, and I want to know if shielding is normally used, and can a Compass chip be used inside a Faraday cage?
Cheers,
Camerart

Hi I and E,
These modules are 1.6x1.6mm on a 10x25mm PCB. I was thinking about insulating them, then sticking copper tape over them, and grounding it to the bottom GND of the PCB.
I used to 'do' a demonstration in an electric museum, where a round magnet was dropped down a tube of plastic, and it dropped straight through. Then drop the same magnet down a copper tube and it took much longer to arrive.
If I 'did' the tape thing, then calibrate it, would it then be protected from electrical interference and capacitance (the signal changes when a hand is near)?

Back to the original question - a non-ferrous screen around the compass element should reduce electrical interference from other things without affecting the compass itself.
Copper or aluminium foil or fine mesh should work.

I use a compass to aim my TV antenna in the correct direction according to TVFool. A cheep $1 compass causes me less trouble than a expensive compass. The expensive compass picks up metal so easy I need to be 20 ft away from all metal to get a good reading. $1 compass works fine 8 ft from metal antenna. If your compass chip sensitivity can be reduced it might work better.
