If you’re interested in any Arduino boards then I recommend checking-out the new Arduino Q&A site over on Stack Exchange. (It’s totally free to use.)

As with most Stack Exchange sites, it was in private beta for a couple of weeks to get it started. It’s now gone into public beta, which means it’s fully functional and anybody can join in. It’s a great place to go if you need help with specific Arduino problems, or if you’ve got some awesome expertise that you want to share.
