i don't quite understand, is this for arduino and raspberry pi? I understand comment 1 that the language may not be correct for the platform, but it doesn't come right out and say whether this is for RasPi and/or Arduino although it would appear so since it as -uino in the name. I see they are offering their own board, is this a language and board, neither both or separate? Kinda super confused here.
