RBBB - Really Bare Bones Board - Freeduino - Arduino-Compatible

This is a mini board designed for those experimental applications that require small processors, such as wearable computing, near space experiments, toy prototyping, artist's projects or any use for a fairly small microcontroller. As far as we know, it's the smallest and most low-cost Arduino-compatible available right now.

Board Specifications:

Size: 2.2" (55mm) x .6" (15.5mm) without the programming right angle headers.
Size with headers: 2.4" (62mm) x .6" (15.5mm).
Height from bottom of board with no breadboard pins: .45" (12mm)
Total height with breadboard pins: .75" (18mm)

Yes, I know the name is uncreative. You can call is Mighty Mite or something cute.

Yes, I know it says RBBA, but pretend it says RBBB, it will soon.

Here's a screen capture of the layout. Basically, a resonator, low-dropout regulator, a couple of caps and some header pins.

Our new bootloader makes the bootloader issues irrelevant. You can read about it here. You can easily stub in the capacitor for full "Diecimila-like" software reset compatibility if you want the software reset.

Cute isn't it. It's only available as a kit right now. You can build a RBBB in a half hour, even as a beginner. The labels on the pins are necessarilly small, to fit on the board. You can read the labels better if you don't use a socket, or boost the socket up by a millimeter, by shimming it off the board with some resistor leads while soldering.
