External Compass Recommendation

I’m planning on designing a custom board with an external magnetometer. What IC’s are currently supported? I see drivers for the HCM5883 and IST8310 and are these the only two so far? Has one been getting better performance over the other?

I am curious about this matter too.
Also wondering if IST8310 has been tested or not.
Any experience with using IST8310 as external compass?

Various manufacturers started to use it and it seems to perform OK.

Also try the LSM303D as an alternative. We’ve tested that one successfully too.
