I haven't tried it out though. I'll add this part to my wish list :)</p>

This is a bundle of sensors that can be used to <em>make</em> a tilt compensated compass. There's lots of computation involved in going between magnetometer readings and compass readings (see the app note).</p>

I know there is a penury with that chip.</p>

And combined with the HMC5843 EOL.. it could be a tough couple months for UAV nerds. :-\</p>

The HMC6343 does. The HMC6343 also has a built in temperature sensor if I'm reading the datasheet right.<br>
In my opinion, the LSM303 should be should be called a "3-axis accelerometer and 3-axis magnetometer" because of this. You can use it to get pitch, roll, and heading.. but you need a uC to do some maths to get these values (the diydrones site and the app note on this page have helpful information on calculating this).</p>
