Why does my GY-271 not respond at address 0x1E?
Some boards marked GY-271 use a QMC5883L chip instead of the HMC5883L. The QMC5883L uses address 0x0D and a different register map, so check the chip marking on the board and use the matching library.
Does the compass need calibration?
Yes. Magnetic interference from nearby metal, wires and magnets causes offsets, so rotate the module through all directions to collect min and max readings, then apply the hard-iron offsets in your code for accurate heading.
