This is the extremely popular Arduino Uno R3 - based on the atmega328P processor. It's the perfect Arduino board to get started with. We are now stocking the latest Revision 3.
If you're new to Arduino have a look at our Arduino Uno Starter Kit. It has everything you need to get started with Arduino!
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).

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
Please note: The Uno R3 works with all existing shields.
The new Arduino boards use different drivers from previous versions - please refer to these instructions if you are having issues.
