Product overview

Arduino Uno SMD is a version of the Arduino Uno, but use atmega328p surface encapsulation and not into the encapsulation. It has 14 digital input/output pin (six of them can be used as a PWM output), 6 analog input, a 16 MHz crystal oscillator, a USB connection, power supply interface, an expansion head, and a reset button, only need to connect to the computer USB cable or dc power supply or use ac/dc adapter or battery can make it to work. UNO SMD is different from the previous version, it serial conversion not use FTDI USB serial port driver chip, it is to use the USB serial port conversion chip atmega8u2. "UNO" means a named Italy and mark the upcoming Arduino 1 release, will be reference for the Arduino UNO and 1 edition version, UNO is a series of new USB Arduino, reference model and the Arduino platform.
