The link you gave points to an overview of the differences between the older version and the newer Gold version (v5).
Yes, there are links to the new schematic, BOM, and mfg'ing data files, but the link still has a link that points to Dave's original detailed article about the old version (As published in the April 2009 issue of Silicon Chip Magazine).
I believe we would like to see the article revised to reflect the new Gold version. The original article is well written and would serve as an excellent "official" User Guide for the product. It is a shame it has not been updated.
