This is the extremely popular Arduino Uno R3 - the perfect Arduino board to get started with. We are now stocking the latest Revision 3, which has the following updates from the last version:
- ATmega16U2 instead of the 8U2 found. This allows for faster USB transfer rates.
- No drivers needed for Linux or Mac (.inf file for Windows is needed and included in the Arduino IDE)
- The ability to have the Uno show up as a keyboard, mouse, joystick, etc.
- New SDA and SCL pins next to the AREF.
- Two new pins placed near the RESET pin. One is the IOREF that allow the shields to adapt to the voltage provided from the board. The other is a not connected and is reserved for future purposes.
- Reset button moved from center of board to corner near USB connector, allowing resets when shields are connected.
- Larger heatsinking copper area for the LM117 regulator

The new Arduino boards use different drivers from previous versions - please refer to these instructions if you are having issues.
Here's the basic 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).
- ATmega328 microcontroller
- Input voltage - 7-12V
- 14 Digital I/O Pins (6 PWM outputs)
- 6 Analog Inputs
- 32k Flash Memory
- 16Mhz Clock Speed
Please note: The Uno R3 works with all existing shields.
