UNO R3 board is 100% compatible with Arduinos , now it has quality and performance .
Arduinos is an open-source physical computing platform based on a simple i/o board and a development environment that implements
theProcessing/Wiring language. Arduinos 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 can be downloaded for free (currently for Mac OS X, Windows, and
This is the new Uno R3. In addition to all the features of the previous board, the Uno R3 now uses an ATmega16U2 instead of the
ATmega8U2 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.
Uno R3 requires the Arduinos 1.0 drivers folder in order to install properly on some computers. We have tested and confirmed that
the R3 can be programmed in older versions. However, the first time using the R3 on a new computer, you will need to have Arduinos
1.0 installed on that machine.
