And I'm responding again to note that I think I interpreted "kit" wrong. I was thinking "kit" as in § 15.23, which gives an exemption for stuff you build yourself but not stuff you build from kits.

But 47 CFR § 2.803 gives an exemption for "evaluation kits". I don't think that clearly covers boards used primarily as single-board computers (and not genuinely for evaluation), and I'd guess that's why the Pi developers got certs for their boards. I believe it's the best argument that this board wouldn't need certification (or verification), though.
