Compass support issues

Hello
Recently, I made a board that intergrated the Compass, the power supply and the GPS.
Because I’m a beginner with the pixhawk, and I’m not a native English speaker. So I chosse the BMM150, because it’s much more cheaper and reliable. It’s the ardupilot support this IC? If not do we have a support list ?

Yes, after I check the source code, I figure it out too, the BMM150 should be supported. but I did not see any wave on my Oscilloscope.
