GY-271 QMC5883L 3 Axis Compass Sensor

GY-271 Compass Module is designed for low-field magnetic sensing with a digital interface and precise orientation Perfect for giving information. This compact sensor fits into small projects such as UAVs and robot navigation systems. The chipset used in this module is QMC5883L. The sensor converts any magnetic field into a differential voltage output in 3 axes. This voltage offset is the raw digital output value which can then be used to calculate directions or detect magnetic fields coming from different directions.

 

QMC5883L and HMC5883L are basically the same, they share the same hardware design. Only the registers are slightly different and we need to change the software slightly. You must use the QMC5883L compatible arduino library.
