Adafruit Industries came up with an alternative to the DC BoArduino that upgrades it to USB. Think of it as an Arduino Duemilanove, with a DIP ATmega328P, that is only half again the size of the Arduino Nano. The DIP packaged ATmega328P is what sets this thing apart from the other small form factor boards. When you get code running on the breadboard, you can pull the ATmega328 and put it in a project. Plug another ATmega328 in the socket and start the next project.
The USB BoArduino has no DC power jack, but instead uses the USB port for power. It is programmed just like the Arduino Uno. Because it has a USB converter chip, it has a 3.3V supply output.
