Arduino Uno R3 (Compatible)

The Uno R3 now uses an ATmega16U2 instead of the ATmega8U2 found on the earlier Uno boards (or the FTDI found on previous generations). This allows for faster transfer rates and more memory. No drivers are needed for Linux or Mac and the Windows drivers are included in the Arduino IDE.

The Uno R3 also adds SDA and SCL pins next to the AREF. In addition, there are 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 not connected and is reserved for future purposes. The Uno R3 works with all existing shields but can adapt to new shields which use these additional pins.

R3 Improvements:

• SDA and SCL pins next to the AREF. TWI interface and IOREF in the top and bottom connectors. This change keeps the board 100% compatible with the current boards and shields, but adds possibilities for new shields.
• Reset button moved from center of board to corner near USB connector. This makes it much easier to access with a shield on.
• Larger heatsinking copper area for the LM117 regulator.
• Atmega16U2 replaces the Atmega8U2.

Features:

• ATmega328 microcontroller
• Input voltage - 7-12V
• 14 Digital I/O Pins (6 PWM outputs)
• 6 Analog Inputs
• 32k Flash Memory
• 16Mhz Clock Speed

Note: This is an Arduino compatible Uno board. It comes packaged in an anti-static bag instead of the retail boxed version.
