Yeah, I've gotten that impression from reading this forum.
I'm a "maker", and I just started doing PCB design a few months ago. I've done a few boards so far with OSH Park. I've been using the libraries that come with KiCad. (And when I've needed symbols or footprints that aren't part of the KiCad libraries, I've created them and then contributed them back.)
The MacroFab libraries are CC-BY-SA 4.0, so that shouldn't be a problem. I could just copy the libraries I'm using into my project's repo, for easy sharing.
Thanks! That confirms my suspicions.
Is there another fab you'd recommend for doing assembly of one-off boards without costing a fortune?
I've been using OSH Park so far, and have been very happy with them for through-hole boards, but my soldering skills aren't that great, so I'm afraid to try SMT hand-soldering. So in order to be able to use SMT components, I'd like to find a fab that can do assembly.
That is a bonus of contributing libraries back to KiCad. The KiCad librarians check your contributions against the datasheet, and several times they've caught errors I've made.
