Arduino Uno Rev3 SMD

Description

The Uno differs from all preceding boards in that it does not use the FTDI USB-to-serial driver chip.

Additional features coming with the R3 version are:

  • ATmega16U2 instead of 8U2 as a USB-to-Serial converter.
  • 1.0 pinout: added SDA and SCL pins for TWI communication placed near to the AREF pin and two other new pins placed near to the RESET pin, the IOREF that allow the shields to adapt to the voltage provided from the board and the second one is a not connected pin, that is reserved for future purposes.
  • stronger RESET circuit.
Microcontroller ATmega328P
Operating Voltage 5 V
Input Voltage 7 V - 12 V
Digital I/O Pins 14
