Here is one for $50 from Devantech. It uses an I2C interface. Never tried i=
t, but sounds like what you're looking for. Let me know how it works out if=
 you use it.

Hi all,

Can anyone point me to a good electronic compass module with serial output
suitable for use in an embedded system? I thought these were plentiful but
when I did a search all I found were really expensive ($300) ones from
Honeywell and then really cheap older designs (like the Vector and Dinsmore=
).

Thanks,

Sean
