"Hello, World" from XOrduino/XO Stick

Here's a quick look at the next versions of the XOrduino and XO Stick boards. These were assembled from a small quantity of "pre-B1" boards I had made at BatchPCB.

I've uploaded some more pictures to the XOrduino album as well.

Here's a little table relating the board versions pictured with those I've previously discussed.

B1 is "the next run" of boards, already released to the fab house but not yet in hand.

The big feature added to XOrduino after A1 was a motor driver, to allow using the XOrduino as a Turtle robot. The big feature added to XO Stick after A1 was the shield form factor, allowing it to ride piggy back on the XOrduino. This makes it easier to share a single turtle robot with a classroom: there may be only one XOrduino robot base, but each student can have their own low-cost XO Stick "brains". They can take turns snapping their brains on top of the base to drive it.

I haven't finished testing all the functionality of these new boards yet, but it looks like I haven't made any major mistakes! Help still wanted with software, documentation, etc; send email to xorduino@gmail.com if you're interested.
