I dream of an open board like the yubikey nano. This is very nice!

A founder I know is making reduced-pin Arm-based prototyping modules: https://www.bergsonne.io/

They're seriously tiny; basically answering the question, "What if mechatronic prototypes didn't need to be the size of an Altoids tin?"

If you are talking about USB-A Nanos, there is https://tomu.im/, which is very nice and interesting.

I’m very familiar, we made Somu :) I meant USB-C.
