The GY-271 is supposed to have an HMC5883L, but some boards have a QMC5883L which has the same basic capability, but is not compatible with the H. The GY-271 QMC5883L 3-axis Electronic Compass Module Magnetic Field Sensor is designed for low field magnetic sensing with a digital interface and it is perfect to give precise heading information. If you get a GY-271 board and observe an I2C address of 0x0C and read back nothing but zeros from the board, then you probably have a QMC5883L chip! Try this library and see if it works for you.
