Arduino UNO R3 MEGA328P with ATMEGA16U2 (Compatible) Development Board

ARDUINO UNO R3 ATMEGA328P WITH ATMEGA16U2 (COMPATIBLE) DEVELOPMENT BOARD

Product information
This Arduino UNO Rev 3 compatible development board is constructed to Arduino’s exacting standards from the original open source schematics and board layout as published on their website. The Arduino IDE is freely available from www.arduino.cc. The website has extensive material and example sketches to use on their boards. Interfacing to a PC is as simple as plugging in the board via the included USB cable and installing the IDE software. Development is simple, easy to understand and suitable for beginners to explore the exciting world of microcontrollers.

Specifications
Uses an ATmega328P
Rev 3 boards now have an added SDA and SCL pin near AREF pin and two other new pins placed near the RESET pin.
The IOREF pin enables shields to adapt to the voltage provided from the board
Has a stronger RESET circuit
ATMEGA 16U2 replaces the 8U2 found on the Rev 2 model
