This circuit is NOT an HMC5883L and cannot be programmed as such. It is still a 3-axis magnetic sensor, just not an HMC5883L. It is actually a QMC5883L, which has different register locations. To find the correct data sheet for this circuit do a web search for "3-Axis Magnetic Sensor QMC5883L". The PDF name is QMC5883L-Datasheet-1.0.pdf Having said all that, this is still a great circuit and works fine, you just need to know what you are dealing with.

Still works excellent but make sure you use code for the QMC5883L instead of HMC5883L chip otherwise the sensor will not work. Other than that it still works well. A lot of the GY-271's have Chinese chips these days.
