We are waiting for stock, which will be due in about two weeks (but
might well be late). We'll be getting 300 units, so that should be
enough for a while.
I should perhaps make it clear that I've no intention of experimenting
with this mod myself, and advise anyone wanting GPIO to use the
single-port version of the board with a hub. This is for a number of
1) We started supplying this board because people requested a 2nd USB
2) The interconnect is flimsy, making it harder to re-house the dual-
in another box, unlike the single-port.
3) The dual-port is less 'Arduino-like' meaning it's not so likely to
replace it in similar sized application.
4) The 2nd USB port can be used for your GPIO application anyhow.
It's certain that anyone getting this working will post here,
In the meantime, I guess you'll just have to wait.
