Amazing. "Become the USB"
What do people use the *OMU (TOMU, FOMU, QOMU, SOMU, ...) boards for? I think the idea is cool, but can't think of any applications for a dev board with basically no IO
Might be interesting to keep some cryptographic keys in there? It's smaller and more hackable than a SoloKey, so if you manage to wire it up to LUKS or use it as a FIDO2/U2F token you've got something that you can take out of your computer and put in a wallet?
(Admittedly, something which doesn't match the hardware security or build quality of a Yubikey, but it's more open and there's definitely some that will value that...)
