31 Mar 2013: Follow-up images from the designer
Here is a follow-up from the designers, showing progress so far. Samples for the Micro-USB, Micro-SD and SIM Card arrived; the Micro-USB was compatible but the Micro-SD was deemed to be inconvenient, both for manual soldering as well as for later mass-production. The SIM Card turned out to not have a locking mechanism (hard to tell from the datasheet). So a decision has been made to leave 3G until the next revision, leaving the Mini-PCIe slot as intended by the client: for USB-based WIFI modules only.
Overall the specification of this tablet will be on the high end for connectivity: dual USB ports and dual Micro-SD cards, because the EOMA-68 CPU Cards will typically have one USB and one Micro-SD.
