Uno R3 - Clone Original Chips original FTDI ATML MEGA16U2

The UNO R3 is backwards compatible with the Arduino UNO - same driver, same uploading, same look. Uno R3 - Clone original FTDI ATML MEGA16U2 Description • 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 Documents For getting started for Arduino book ,Click Here For simply Arduino(أردوينو ببساطه) book in Arabic ,Click Here Uno R3 revision 3 schematic Arduino uno R3 page Arduino uno R3 software download
