Yeah the low density 40pin GPIO sort of seems legacy now that often isn’t RPI 100% compat so why.
Khadas dropped the 40pin on there edge2 which soon as I saw thought yeah been thinking that for a while, not sure if they could of gone for cheaper FPC connectors though…
With model A type boards I would say both and wondering what concessions, some would promote.
Dunno about the garbage from wafers as it would be unusual to offer less interfaces and retain same rated freqs, guess we will have to see how the https://www.khadas.com/edge2 does as more users test as sure they will.
Khadas often make some really nice boards but often seem to have a really nice premium.
So a lot of dunno as merely interested in what is possible cost wise with a rock5a and can not say until I see them become a thing.
I guess you do what Radxa are doing and release full fledged model-b’s and get a feel for community use and feedback.
