Im pretty sure the device they pictured is a mockup, for them to test the software on, remember every company has different requirements, some may require multi-port devices etc, so i'd imagine the team would have a plan to test and then develop larger boxes, in the end they just have to get it working on ARM (raspberry pi) and then they can port that work over to other ARM boards.
