That should have read SMD. Anyway, the Wiz105SR just barely fits on a shield PCB with enough room left over to squeeze in a 2x6 header that can connect to the module via a ribbon cable. So, while I'm waiting on answers to a couple of questions, I'm fairly sure I'll design a shield for the Wiz105SR and the WizFi210. Both are among the least expensive modules of these types. If so, I'll drop the shield design for the Tibbo modules - I really don't like how long Tibbo took with firmware updates nor do I like the Goldbergian interconnect method they used between the EM500 and GA1000 and flash.
