Indeed, but as far as USB is concerned, there's more similarity than difference.

Interesting.

Thanks.

Yes.  Footprint only.  And I love the idea of holes in the board to
strap down the cable.

As for the connector placement on the original board, I'm thinking
it's fine for the -8/e/f/m, but it might be in an awkward place for an
-8/a.  What you have been describing for this new board sounds like it
will be good for both (conveniently for me, I have both types of
boxes...)

Thanks!
