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.

In my first year of electronics engineering school, I learned how to insert socketed chips. I broke a few and screwed up a few times, but after the first few weeks I was pretty good at it.
Also, there is no place to put the little rubber feet that come with it. They're too wide to fit between the various pins on the bottom of the board
Looking thru the Amazon reviews showed great ratings, BUT there were a few issues that popped up in some reviews. Some indicated that they received fake Arduinos. A few said there were some quality issues.
Issue 1 - Fake Arduino? An online post suggested that the Amazon seller be cross checked with "approved" vendors as listed on the official Arduino web site. I purchased mine through Karlsson Robotics, and they are indicated as an approved Arduino "supplier". The first thing I did when receiving my Arduino is to check all the standards means of detecting a fake. Every item checked out, in particular the gold 504L device. I am 100% assured that this is a product from the factory in Italy.
Issue 2 - Quality? The quality of the board, solder joints and devices appears to be just about perfect. There are no instances of incomplete or rough solder joints. Everything is soldered in a super smooth manner, probably from one of their production machines. It's an outstanding job. So far I've done a few operations with the board, and no issues have been observed. The board connected easily to the computer via an A-B USB cable (not included with the board).
Karlsson Robotics is a legit supplier, and they provided my Arduino board with zero issues. Highly recommended that you purchase though them. The Arduino board is top notch, and is ready to go out of the box.
