• I'd like edge headers in 2mm and 2.54mm pitch with a trace to a neighbour through hole pad (I.e exactly what the Espruino has on the edge opposite to the usb) so it's easy to route i/o to a header/plug.

    Having a plethora of various SMD fooprints would be awesome too! For me the optimal would be to have through hole pads next to the smd pads (will constrain space though, and again this is so I could use jumper wires for quick prototyping).

    Maybe it would be an idea to make two variants, one for SMD and one for through hole. It would also be cool to allow the protoboards to connect to eachother with say an edge connector and using the pcb as a plug into the next.

    I have a lot of surplus SOT-23 and 0603 components, so thouse would be a high priority for me but probably not for the next guy.

    Something like:

    This board has a lot of options, and a nice way of doing multiple pin counts:
