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. To install this library into your Arduino environment, download the latest release file to your desktop: latest released files

This compact sensor fits into small projects such as UAVs and robot navigation systems. The sensor converts any magnetic field to a differential voltage output on 3 axes. This voltage shift is the raw digital output value, which can then be used to calculate headings or sense magnetic fields coming from different directions.

A development board that provides a simple interface for the HMC5883L (three-axis magnetic field module).

HMC5883L and QMC5883L module don’t have too much difference. HMC5883L is made by Honeywell. but because the production is about to be stopped, so we use a similar compass module-QMC5883L instead. QMC5883L is made by a Chinese company, they get the production authorization of HMC5883L from Honeywell, and rename it QMC5883L. So QMC5883L and HMC5883L basically are the same, they shares the same hardware design. Just their register is a bit different. We only need to change the software a bit.

When you got the product, please check which compass module you get. The HMC5883L has a label “L883″on it, while QMC5883L comes with “5883”. Please visit this link for more information. The information regd. HMC5883L(Or QMC5883L) Electronic Compass is also provided in the attachments.

    chip is great, why you are you trying to discourage people from buying it by writing china chips.
