Reliable orientation data
Using this for a DIY drone project. The magnetic field readings are stable after calibration. Compact size fits well.

Good sensor, tricky calibration
The hardware is solid. Just be aware you need to calibrate it properly to get accurate headings. Instructions could be clearer.

Bulk purchase for class
Bought ten for our robotics class. All units functioned correctly out of the box. Great for teaching I2C communication.
