Arduino NG PLUS USB Board, fully assembled
Arduino is a tool for making computers that can sense and control more of the physical world than your desktop computer. It’s an open-source physical computing platform based on a simple microcontroller board, and a development environment for writing software for the board. Arduino is open source!

Arduino Mini Board, fully assembled
This miniature Arduino board has an ATmega168 onboard, which offers twice as much program space as the ATmega8 on the other boards (16 KB vs. 8 KB). You can plug it in a breadboard or put it in a socket soldered into prototyping board. Like the full-sized Arduino boards, this runs at 16 MHz.

Arduino Mini USB Adapter, fully assembled
This board converts a USB connection into 5 volt TX and RX that you can connect straight to the Arduino Mini or other microcontrollers, allowing them to talk to the computer. It is based on the FT232RL chip from FTDI (drivers are included with the Arduino software).

All this and more @ the Maker store! – Link.
