The Arduino Nano is a small, complete, and breadboard-friendly board based on the ATmega328 (Arduino Nano 3.x). It lacks only a DC power jack, and works with a Mini-B USB cable instead of a standard one.
Comparison with Arduino UNO
Digital IOs: Arduino Nano and Arduino UNO have exactly same number of Digital IOs (i.e. 14)
PWM Channels: Arduino Nano and Arduino UNO have exactly same numbers of PWM Channels (i.e. 6)
Clock: Arduino Nano and Arduino UNO have exactly same clock frequency (16.000 MHZ)
Flash Memory: Arduino Nano and Arduino UNO have exactly same amount of flash Memory (i.e. 32KB)
Data Memory: Arduino Nano and Arduino UNO have exactly same amount of Data Memory / RAM (i.e. 2KB)
EEPROM Memory: Arduino Nano and Arduino UNO have exactly same amount of EEPROM Memory / RAM (i.e. 1KB)
