The Arduino Uno R2 is a microcontroller board based on the ATmega328. It 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.

They will just end up giving the Arduino Project's work a bad name, and I cannot support them. I did not receive a surface mount board like others have. Clones are perfectly legit, but it is wrong to pretend to be an official board and not have a manufacturing location marked on them, and then cleverly alter the official Arduino markings to say "Designed in Italy" instead of Made in Italy.
As an aside, it wasn't the latest revision R3, but an R2 board, but at least the web image was an (Offfical) R2. Just buy an official board. Support the good work of the Arduino project.
Best case, it was not an R3 board, but an earlier version.
Worst of all, though, was that USB connectivity was sporadic to non-existent. I couldn't reliably connect it to my computer.
Rather than fight it, I purchased an official R3 board from Mouser. It came in an official sealed Arduino box, and is an R3 board. The silkscreen says made in Italy. The best part is, this board works.
NOTE TO BUYERS: This listing is for the Arduino Uno SMD edition, meaning the microcontroller is surface mounted, rather than socketed (as is shown in the product image). Both the socketed and SMD edition are functionally identical, with one difference:
if you want to use the Arduino Uno board to program an Arduino Mini board (without having to additionally buy the Mini USB/Serial Adapter), you can simply remove the socketed chip and run jumpers to the Mini. But with the SMD version, you can't remove the socketed chip to do this.
P.S. don't relegate this board to the Toy market. While it's great for kids who want to use a micro-controller to build a project around, it's in a far different league than a Soda Can robot. This would be great board for College students to build design projects around, artist to add automation to their work, or anyone to prototype off of. Also, I don't know how long the board will last, or what it's duty cycle is, but it has plenty of capacity for home automation projects too.
