The USB area is going to bug me. I'm almost thinking 3D printed panel slot doodad. But my original idea was so much simpler - fabricate a nice little mylar cover that I can churn out on my electric cutter.
Need to find a much smaller right angle button and another with a long button stem, perhaps.
I really don't want to abandon the big honkin' USB-B connector. It seems appropriate since the SDL was so hardcore.
Otay. Now that I'm thinking out loud, Micro USB in bluetooth applications, with a smaller PCB that can be stacked over top with buttons/LED(s)/power switch. Smidgin bit more complicated, but less complicated than other alternatives I suppose. It'll look nicer and that will make me happy. Plus they'd be super cheap to have manufactured.
Looks like the ezkey modules are out of stock so I'll have to wait to buy one to fiddle with. I suppose elegant support will be in version 2.
Picture: Help! I can't get the firmware to load on paper! :X
