cheap digital compass, does anyone have experience with it?

Hi LMR people,

Looking for a digital compass for my robot, I found this interesting Dual-axis Magnetic Sensor Module with UART& I 2 c Interface for $16.

8$ compass

4 weeks ago i ordered the dc-ss503 magnetic sensor module with tilt compensation, and i'm now trying to interface it with arduino. so far i have obtained the 4 values from the i2c bus, but i can't understand how to actually get a heading from it. this is the datasheet i found, which i know is the right one: http://gongxue.cn/lixueyuan/UploadFiles_8285/201004/2010042114001679.pdf .

does anyone have any experience with this module and can possibly help me? thanks
