Raw Android Hardware

Here is a picture from Google I/O which appears to be raw hardware that runs Android. It might be part of Google's Android Developer Kit.

But as you can see this hardware has Google Android on it and it says "Accessory Demo Shield."

Jeff Seelig took the picture last week while at Google's Mountain View office area using his Nexus One (the first generation Google phone). He tagged the picture as ADK, which means Android Developer Kit, I believe. The original picture can be found on Flickr.
