DW3000 "missing manual" notes

Overall

The DW3000 is an exciting part, available as a convenient Arduino-shield eval board with good distribution. HOWEVER, this is NOT a "maker friendly" part with SparkFun or Adafruit type tutorials and examples! It is a sophisticated radio that can be the heart of a positioning system, but you have to do quite a lot of heavy lifting to get there.

For basic use, the older-but-still-good DW1000 may be a better choice; interface libraries are available for Arduino and Raspberry Pi. Or look into packaged location-system vendors, like Estimote, Pozyx, Ubitrack and many others
