The Arduino Uno is a microcontroller board based on the ATmega328 (datasheet). 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.

The Uno revision 3 differs from all preceding boards in that it does not use the FTDI USB-to-serial driver chip. Instead, it features the Atmega16U2 programmed as a USB-to-serial converter.

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; An IOREF pin that will allow future shields to adapt to the correct IO voltage and second not connected pin that is reserved for future purposes.

 Stronger RESET circuit.
 Atmega 16U2 replace the 8U2.

Please note that this item is Arduino compatible. Arduino is an open standard and this board has been built exactly to the Arduino open source reference design. It also contains the same boot loader and is therefore identical in design, build and software to an original board. The only significant difference is the price. All our Arduino boards are built and tested at the same factory and have an exceptionally high reliablity rate. Of course, if you are not happy with your order you can return it back to us for any reason within 14 days of receiving it.
