Each such chip includes a processor, memory and supporting components ... the most popular UNO R3 must evolve, though we have no plans to discontinue the board,” said Arduino co-founder Massimo ...

Original Circuit Diagram: Arduino UNO R3 Now, have a look at our favorite Arduino UNO to find out the AVR chip inside. It is ATMega328P-PU, a low-power version of the traditional ATMega328-PU. The P ...

Then, chances are you already know what an Arduino is ... In fact, the original Uno has already been retired. That said, we'll be focusing on the Uno R3 in this discussion instead.
