If there is eventually a Ya Nanonote, USB Host will be our friend on so many levels. In my opinion the right connector will be standard USB A.
The more I noodle about useful variants of Ben, the less I think >>>> FOR MY USE CASES <<< (your mileage may and will vary) that retaining Ben plastic case matters. In a perfect world, Ben 2.0 PCB fits inside existing Nanonote case, but has some things that can be soldered on after the fact when used in a larger not so pretty more industrial case that's not for your pocket My vision is Ben as central network manager (more or less) talking to any number of external devices thanks to the ongoing 8:10 work by Werner. That port might talk to a smart but cheap bridge device that has (most likely) AVR chip that understands a simple protocol Ben sends then does the right thing with it's own attached devices. My first target would be the COOL stuff from JeeLabs, but there are PLENTY of other devices in that space. They may be Arduino inspired *as is JeeLinks) or could use other cheap low power MCUs such as Ti MSP 430 (you can buy the launchpad COMPLETE for $4.30 in USA, including shipping. That is hard to beat. Ben would provide human interface, and talk to Launchpad or other devices using a simple protocol. I discovered such a protocol a year or two ago, now I have to re-find it. Maybe Carlos (no longer here) can refresh my memory. Bottom line: my world view pushes real time to intelligent external devices, with Ben resonsible for communicating a stream of bytes to an external device this byte stream is composed of simple control messages. In return, the external device reports back to ben, again using a simple protocol over a stream of bytes. (more than) enough for now --- Ron K.
