Hello community!
Yesterday I received my Framework 13, and I already have something in mind to create: an expansion card that can be used to interface UART. The external side of the card would expose a 3- or 4-pin header.
What makes this a bit more interesting is that I’m also considering designing a casing for the expansion that can be attached using N35 magnets (like this). This would allow the IC to be swapped out for something else.
I’d appreciate any suggestions, tips, or things I should watch out for—both on the electrical side and the mechanical design.
