UNO R3 board that is 100% compatible with original Arduino.
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.
To use this as CNC electronics you will need the expansion board CNC shield and drivers that is avalible on our site
