There are many -duino boards out in the market place and many more probably being developed all the time.
Some we will never know about because they would be developed and probably not shared with the community but worthy of the -duino tag.
At the same time there will be just as many produced on the back of the open-source material for certain applications.
So the question is .... would there ever be a limit to the '-duino' concept?
I'd be interested to know, especially when so many educational establishments are beginning to pull these into their course work.
Any thoughts would be welcome.
