The Arduino Uno SMD R3 is a microcontroller board based on the ATmega328, microcontroller Uno SMD Development board, 2KB RAM, 1KB/32KB, EEPROM/FLASH, 16MHz. USB Host Shield for Arduino UNO MEGA 2560 1280. Support Google Android ADK USB HUB.

Microcontroller Arduino Uno Rev3 SMD Development Board

Arduino Uno Rev3 SMD board has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog 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.
