Recommendations to the author: 1) As others have said, a version with black on white illustrations would be massively useful for printouts. 2) Bookmarks/Table of Contents. While I was happy to see the headings in the ToC in the book itself were clickable, there's only one bookmark in the PDF and that's randomly for page 298. 3) Why distribute it as a zip file, 3.8 MB vs 3.5 MB doesn't seem worth the hassle. 4) A miniature lineart on the pinout chart pages would be nice too. 5) USB Type Micro B is listed 3.0 then 2.0, but the other USB ports are listed 2.0 then 3.0, likewise the Micro B appears before all the other types, but Mini B is after the USB B connectors 6) You have firewire 6 pin, but not 8 pin or 4 pin 7) The board on page 264 looks like it should be a Rock Pro 64, but it's labeled Rock 64 like the previous board Because I don't like to just complain, I've created a bookmarks text file that can be applied to the PDF using JPdfBookmarks and includes some of the corrections I've noted above. There doesn't appear to be a feedback/suggestions link on the site, so here's a link to a repo instead https://gitlab.com/tpmoney/pinouts.org-pdf-bookmarks https://gitlab.com/tpmoney/pinouts.org-pdf-bookmarks
