The board needs a few modifications, so I guess we need to prepare rev.B for better user experience.
Please don't use the old rev.A gerbers for manufacturing.

what sort of modifications are these? btw, what's the ballpark estimate for its manufacturing costs? (jlcpcb?)
brilliant job, amazingly compact board!
