Arduino Uno – R3 Original – Made in Italy




This is the new Arduino Uno R3 made in Italy with box. In addition toall the features of the previous board, the Uno now uses an ATmega16U2 insteadof the 8U2 found on the Uno (or the FTDI found on previous generations). Thisallows for faster transfer rates and more memory. No drivers needed for Linuxor Mac (inf file for Windows is needed and included in the Arduino IDE), andthe ability to have the Uno show up as a keyboard, mouse, joystick, etc.


The Uno R3 also adds SDA and SCL pins next to the AREF. In addition,there are two new pins placed near the RESET pin. One is the IOREF that allowthe shields to adapt to the voltage provided from the board. The other is a notconnected and is reserved for future purposes. The Uno R3 works with allexisting shields but can adapt to new shields which use these additional pins.


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


Note: The Arduino Uno R3 requires the Arduino 1.0 driver’s folder inorder to install properly on some computers. We have tested and confirmed thatthe R3 can be programmed in older versions of the IDE. However, the first timeusing the R3 on a new computer, you will need to have Arduino 1.0 installed onthat machine. If you are interested in reading more about the changes to theIDE, check out the official Arduino 1.0 Release notes!
