Arduino Egypt now stocking the latest Arduino UNO Revision 3. The arduino UNO R3 is backwards compatible with the UNO - same driver, same uploading, same look. 


  • There are a few changes in the UNO, here is what they are
  • 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. this is a duplication of the Analog 4 and 5 pins.
  • 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 heat sink copper area for the LM117 regulator
