Hi,
I am working on a project that uses an iPhone 6 compass module AK8963C.

I ma up some PCBs, which sometimes work and sometimes not. Since then I've found correct CAPS etc that IPhone use. On the VID track are 2x CAPS on the VDD track there are 2x CAPS.. The iPhone controls VID and VDD separately, so the reason for 2x CAPS on each track.

For my use I will connect VID and VDD together, so can I only use 2x CAPS?
Any advice welcome.
Cheers Camerart.

Hello,

Pages 33 and 34 of the datasheet show capacitors on the VID and VDD lines.
When they are connected together as VID may be equal to VDD, I would think that even one capacitor would do.

Hi B,
True, I made this PCB using the 1x CAP each but this is intermittent, so I researched and am making the 2nd PCB with a proper Schematic, which as I've said uses 4x all together.
Note, the 2nd SCH is on a phone, that uses frequencies that may need extra CAPS, mine won't.
So with that, do you now think I need 2x or 4x CAPS?

Hello,

Could it be there are problems with the balls for soldering?
The AK8963N has all connections on the side and is slightly bigger to handle:

Hi B,
I've made 5x up to now, and test each track, so I doubt there are ball problems, although possible.
