From the manufacturer
Arduino Uno is a microcontroller board based on the ATmega328P. It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz quartz crystal, 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.. You can tinker with your UNO without worring too much about doing something wrong, worst case scenario you can replace the chip for a few dollars and start over again.
"Uno" means one in Italian and was chosen to mark the release of Arduino Software (IDE) 1.0. The Uno board and version 1.0 of Arduino Software (IDE) were the reference versions of Arduino, now evolved to newer releases. The Uno board is the first in a series of USB Arduino boards, and the reference model for the Arduino platform; for an extensive list of current, past or outdated boards see the Arduino index of boards.

Arduino is the world’s leading open-source hardware and software ecosystem. The Company offers a range of software tools, hardware platforms and documentation enabling almost anybody to be creative with technology.
Arduino is a popular tool for Iot product development as well as one of the most successful tools for STEM/STEAM education. Hundreds of thousands of designers, engineers, students, developers and makers around the world are using Arduino to innovate in music, games, toys, smart homes, farming, autonomous vehicles, and more.
Arduino is the first widespread Open Source Hardware project and was set up to build a community that could help spread the use of the tool and benefit from contributions from hundreds of people who helped debug the code, write examples, create tutorials, supports other users on the forums and build thousands of groups around the globe. We are eternally grateful for being supported by such an amazing community.
This is a genuine new Arduino Uno R3. The Arduino Uno 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 an AC-to-DC adapter or battery to get started. Note From Arduino Founder Massimo Banzi We stress the fact that [genuine Ardunio board from mp3Car.com] are made in Italy because in this globalized world, were getting the lowest possible price for products sometimes translates into poor pay and working conditions for the people who make them, at least you know that who made your board was reasonably paid and worked in a safe environment. (This obviously applies only to the boards marked "made in Italy", we cannot attest to the manufacturing process of "third party" boards). The Uno differs from all preceding boards in that it does not use the FTDI USB-to-serial driver chip. Instead, it features the Atmega16U2 (Atmega8U2 up to version R2) programmed as a USB-to-serial converter. Revision 2 of the Uno board has a resistor pulling the 8U2 HWB line to ground, making it easier to put into DFU mode. Revision 3 of the board has the following new features: 1.0 pinout: added SDA and SCL pins that are near to the AREF pin and 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. In future, shields will be compatible both with the board that use the AVR, which operate with 5V and with the Arduino Due that operate with 3.3V. The second one is a not connected pin that is reserved for future purposes. This is the org version of this product, not the CC.

mp3Car is an authorized seller according to Arduino's official website.
When the item arrived, everything looked legitimate.
It came in its own sealed box that included the Arduino itself, along with stickers, 4 clear rubber pads, as well as small pamphlet that includes information on the Arduino and warranty.
I did my research to ensure I was purchasing a genuine Arduino since the first one I purchased clearly is not.
This one has the yellow chip right next to the USB port, where the counterfeit's are green.
BAD: The soldering workmanship is very disappointing; the worst I've ever seen in a production job. SMT devices on the top seem to be mounted OK, but the bottom of the board had numerous defects in the (wave?) soldering. Two of these joints appear to have been manually touched up (residual flux present). Several other joints had large gaps in cold solder joints, but were apparently not bad enough to warrant manual repair. I hope the Italian manufacturer (SMART PROJECTS) works out these process kinks soon.
*** UPDATE July 2012 *** My subsequent purchase of an UNO-R3 board indicates that the soldering issues in early production boards have been solved. (FYI, CanaKit is an approved distributor for Arduino.)
The Arduino concept is terrific, and has enabled a LOT of people to easily create smart projects. The C compiler and IDE work well; I've never had an easier time writing an embedded application, and the price can't be beat. The only thing lacking is the ability to debug code via single-step.
And on top of that, it wouldn't work when I plugged it in.
Be careful! You're better off buying through a site like Sparkfun or Adafruit.
If you are wondering how advanced this is the sky is the limit. If you can load a computer program and transfer files you can be blinking LEDs the same day you get the controller and you can be writing to the LCD almost as quick. Be advised that the schematic on page 116 shows the pin layout of the LCD 1-16 top to bottom but the illustration is real life 1-16 bottom to top. That caused some frustration. The code that you write to make your sketches is very exacting. Capitalization, punctuation, and spelling is critical. You must write everything EXACTLY as it should be or it won't even try to run your program. If you're easily frustrated and not very exacting you might consider a different hobby.
To do more than basic stuff you're going to have to learn a lot of code and it's not in English as we know it but if you are willing to learn that you can build way more than just clocks, calendars and weather stations.
