I've been working on a pin and software compatible Arduino variant for some time, the Zigduino. It is based around the ATmega128RFA1, which gives it a built-in 802.15.4 radio as well as a good deal more flash and RAM than a standard Arduino (128K and 16K, respectively). It is substantially more electrically rugged than a standard Arduino -- each pin can handle a +/-30V transient.

It is now on sale at http://www.logos-electro.com/zigduino. My sales announcement on my company blog is at http://www.logos-electro.com/blog/2011/6/28/zigduinos-for-sale.html.

Nicely done!  The ATmega128RFA1 is a firecracker.  Nice to see it on a board.  I think I am going to go after one of your prizes.

Have you tested the open air transmit range using the supplied antenna? I do not see any estimates in your product description or any of your documentation.

Chagrin,

Achievable range is subject to a great variety of variables. Since I'm not equipped to do a range test to the applicable IEEE standards, I decided it was better to not make formal claims as to range rather than to make ones that I don't have full support for.

That said, you should see range equivalent to the base XBee module, which is about 300 ft outdoors, unobstructed. Your range may vary.

Aww I've been waiting for another ATmega128RFA1 product on the market but you've taken away a lot of the extra I/O pins (no second USART makes me sad), and didn't give me enough cost savings to justify the missing pins (I take that back... I kind of like it more now). Hopefully you can break-out more pins in another revision
