Arduino Uno SMD Board
The Arduino Uno SMD is a microcontroller board based on the Atmel ATMega328. It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analogue inputs, a 16 MHz crystal oscillator, a USB connection, a power jack, an ICSP header and a reset button. 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 all preceding boards in that it does not use the FTDI USB-to-Serial driver chip. Instead, it features the Atmel ATMega8U2 programmed as a USB-to-Serial converter.
‘Uno’ means ‘One’ in Italian and this board was named to mark the upcoming release of Arduino 1.0. The Uno and version 1.0 will be the reference versions of Arduino, moving forward. The Uno is the latest in a series of USB Arduino boards, and the reference model for the Arduino platform; for a comparison with previous versions, see the Index of Arduino Boards here.
