The Classmate doesn't have any good way for teams to wire in their own buttons/knobs/blinky lights, so this circuit provides that.
I'm not sure how much is public knowledge at this point, so I will just say that it could provide some interesting opportunities for new control strategies. If anyone does know what information has been publically released, please share!
If anyone has any speculated features / wish lists, please share those as well!
Edit:
There was some talk in this thread
