Arduino Uno в отличие от всех плат-предшественниц имеет ATmega8U2 вместо FTDI-чипа. Это позволяет повысить скорость обмена данными и отменяет необходимость использования драйверов под Linux или MacOS (inf файл для Windows требуется). Также благодаря этому Arduino Uno может восприниматься компьютером как клавиатура, мышь, джойстик и т.п.

Характеристики:

• Микроконтроллер ATmega328
• Входное напряжение - 7-12В
• 14 цифровых портов ввода-вывода (из них 6 портов вывода с ШИМ)
• 6 аналоговых входов
• Флэш-память 32k
• Частота 16МГц

Description: Arduino is an open-source physical computing platform based on a simple i/o board and a development environment that implements the Processing/Wiring language. Arduino can be used to develop stand-alone interactive objects or can be connected to software on your computer (e.g. Flash, Processing, MaxMSP). The open-source IDE can be downloaded for free (currently for Mac OS X, Windows, and Linux).

This is the new Arduino Uno. In addition to all the features of the previous board, the Uno now uses an ATmega8U2 instead of the FTDI chip. This allows for faster transfer rates, no drivers needed for Linux or Mac (inf file for Windows is needed), and the ability to have the Uno show up as a keyboard, mouse, joystick, etc.

Special SMD Version: Because Atmel is moving more and more of their production capacity to surface mount ICs, the DIP packaged ATmega328 is becoming more and more difficult to get. To keep up with demand, we now offer the Arduino Uno with an SMD ATmega328. The board is identical to the PTH version of the Uno, but you won't be able to remove the ATmega328 without some hot-air. This change shouldn't affect most users. Besides - when was the last time you managed to destroy an ATmega328 and needed to repair an Arduino board? Those things are nearly indestructible.
