Arrived on time. Seems to work as intended but I've only had it for a couple days. 4 stars because it is a hard to mount without any brackets on boardData sheet: http://www.adafruit.com/datasheets/HMC5883L_3-Axis_Digital_Compass_IC.pdfArduino Guide: http://www.meccanismocomplesso.org/en/arduino-magnetic-magnetic-magnetometer-hmc5883l/Raspberry Pi Guide : http://blog.bitify.co.uk/2013/11/connecting-and-calibrating-hmc5883l.htmlThe Arduino Guide is written in Wiring while the Raspberry Pi guide is written for PythonGood luck, and keep it simple.

Works as intended and comes with both straight and right-angle pins.  The only reason I didn't give it 5 stars is that it does not include the datasheet or example programs mentioned in the description.
