Thanks for the link.

I'm going to order a Xino Basic kit (I usually don't like it when the International airmail postage is nearly as much as the product but will make an exception in this case.). That way I can test any shields I design.

I suspect I can have it assembled long before Tibbo releases the long-promised EM500 firmware that supports the GA1000. And it will only take about a week to get a few boards from CircuitMart or ezPCB as soon as Tibbo confirms the EM500/GA1000 interconnect scheme.

About a year ago they told me they could be assigned in the EM500 program but a lot has changed (except for the EM500 firmware ) since then so I need confirmation before etching any copper.
