3-Axis Compass module, a member of grove family uses I²C based Honeywell HMC5883L digital compass. This ASIC is equipped with high resolution HMC118X magneto-resistive sensors and a 12-bit ADC. It provides compass heading accuracy up to 1° to 2°. Signal conditioning like amplification, automatic degaussing strap drivers and offset cancellation are inbuilt. This grove module also includes a MIC5205-3.3 for power supply requirement. Hence user can connect any 3.3V to 6V DC power supply.

For all Grove users (especially beginners), we provide you guidance PDF documents. Please download and read through Preface - Getting Started and Introduction to Grove before your using of the product.
Please visit our wiki for more info about this product. It will be appreciated if you can help us improve the documents, add more demo code or tutorials. For technical support, please post your questions to our forum.
Hello, you can't use 2 I2C modules in one GrovePi, as they have same address.
And the address of this module is not selectable.
Hello, it's ±5V or ±10V （selectable）
You need to calibrate the sensor in order to find the inclination.Kindly refer the wiki http://wiki.seeed.cc/Grove-3-Axis_Compass_V1.0/
It is ok to do that. You can use solar panel or other power source to supply the board through solar cell input.
I load (and unzip) all programs from your wiki page for this Grove module to arduino-1.0.1\libraries.
Files is not open by arduino-1.0.1, because file extention of your files is not compatible with arduino-1.0.1.
What is wrong?
Hi,maybe you could change a browser and have a try,things like that(http://www.seeedstudio.com/for....
Could i connect that wonderful device directly to an I2C bis with 5V logic level without a logic level shifter?!
hi,there is already a logic level shifter in our product. if you do your products with this IC, please refer to the datasheet.
i connect it direct to the ardurino and its not working
i use this link and download the soft to the board
Hello, there is something wrong with the code, we have modified it, please kindly copy the code and upload to your Arduino again :D
