Project development and debugging of applications is done via a virtual serial port for further information visit the Wiki LinuxStamp.
If you want one his price is $120.00.
ARDUINO MEGA a new version of the super blue microcontroller with the Atmega1280 as brain, this time with a capacity of 127Kb of flash memory, 4KB of RAM and 4Kb memory epprom, here the first images of what will be the clone or improved version of the Arduino, a little reminder of the elder brother of the Arduino the development platform also Open Hardware WIRING.

The CREATE USB Interface (CUI) was a project that came out of UC Santa Barbara around the same time the Arduino was being developed. It has a USB port, a PIC18F4550, and a prototyping area. It was designed to enable easy interfacing with the real would through many A/D inputs and general I/O ports. It supports both OSC and MIDI-over-USB natively. The biggest difference between the CUI and the Arduino is its USB support. The Arduino uses an FTDI chip to create a serial interface to its onboard AVR. The CUI’s PIC has native support for USB. That means you can have the CUI appear to be any USB HID device you want: keyboard, mouse, game controller, etc.
The Arduino has a friendly development environment and a large following though. CUI create [Dan Overholt] decided to add an ATmega168 to his board to get the best of both worlds, the CUIduino (scroll down). It can be programmed just like any other Arduino compatible device, but the having the CUI parent means your Arduino project can behave like a native USB HID gadget.

Matt of Liquidware brings us the elegant and able-bodied open source Illuminato - an Arduino compatible featuring 42 I/O pins, Atmega645 (2x code space of ATmega168) and chic white LED backlighting -
Great standout details on the board such as the side-mounted reset switch and symmetrical layout in black/gold. More videos, info, and insight to the development process over on his blog.
