1)Using Atmega 16U2 instead of Atmega 8U2. Means a higher transfer rate and memory.
2) Without having to install the driver in the Mac and Linux systems. (In the windows system IDE drive)
3) Add the SDA and SCL interface.
UNO R3 board is our new product! It\'s 100% compatible with original Arduino, now it has perfect quality and performance , we believe it will provide exciting use experience to you! 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 Tosduino 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. Note:
The TOSduino Uno R3 requires the Arduino 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 of the IDE. However, the first time using the R3 on a new computer, you will need to have Arduino 1.0 installed on that machine. Package include: 5 pcs Uno R3 5 pcs cable
