The really awesome thing about these being in simple reference designs, is how easy it is to swap out things like that. I really like how they have things laid out, and will be using this as a reference for jr. folks on how to lay out logical blocks in KiCad.

I have often thought how awesome it would be to have a bunch of proven / validated / supported open source blocks for common things like power supplies, sensors, etc. I think that at some point digikey or someone had a modular board that you could mix and match stuff into a reference design, but I can't remember the details.
