I think it would make sense to add a link to all source files or repositories on the downloads link. I know that most source files are available from the diy drones store site, although they are not in a directory structure that makes sense.
The thing that lead me to this suggestion is that I am trying to find the schematic and component values for the air speed sensor board which are not listed in any location I can find.
Link to air speed sensor board with no source listed:
