Arduino Uno SMD Rev3

Arduino Uno SMD Rev3 is a microcontroller board based on the ATmega328. It contains everything needed to support the microcontroller; simply connect it to a computer with a USB cable or power it with a AC-to-DC adapter or battery to get started. The Uno differs from preceding boards in that it does not use the FTDI USB-to-serial driver chip.

Features of Arduino Uno SMD Rev3

 

  • The Uno is the latest in a series of USB Arduino boards, and the reference model for the Arduino platform
     
  • It is a microcontroller board based on the ATmega328
     
  • Contains everything needed to support the microcontroller
     
  • 14 digital input/output pins (of which 6 can be used as PWM outputs)
     
  • 6 analog inputs
     
  • 16 MHz crystal oscillator
     
  • USB connection
     
  • A power jack
     
  • ICSP header
     
  • A reset button
     
  • Differs from all preceding boards in that it does not use the FTDI USB-to-serial driver chip
     
  • Additional features of the R3 version are:
     
    • ATmega16U2 instead 8U2 as USB-to-Serial converter
    • Added SDA and SCL pins for TWI communication placed near to the AREF pin
    • 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
      • Second pin is a not connected, reserved for future purposes
         
    • Stronger Reset circuit
