The Nano V3.1 is a small, complete, and breadboard-friendly board based on the ATmega328 (Arduino Nano 3.0) or ATmega168 (Arduino Nano 2.x).It have an integrated on-board USB. As the function, It has almost all the analog and digital pins that the UNO or Duemilanove has and the same function as Duemilanove or UNO.  As an upgrade version of Arduino Nano, This Nano V3.1 is 100% compatible to Arduino Nano and its shield and IDEs. On the hardware part, remarkable changes are taken to improve the flexibility and user experience. FeaturesPower OK red LED, Green (TX), green (RX) and green (L) LEDUpgraded 5V voltage sourcing, more powerful drive capabilityMini-B USB for programming and serial monitor, TX&RX breakout for application as USB-UART convertorSurface-Mount ICSP headerStandard 2.54mm spacing DIP (breadboard friendly)  SpecificationMicrocontroller: ATmega328Operating Voltage(logic level): 5VInput Voltage(recommended): 7-12 VInput Voltage(limits): 6-20 VDigital I/O Pins: 14 (of which 6 provide PWM output)Analog Input Pins: 8DC Current per I/O Pin: 40 mAFlash Memory: 16 KB (ATmega168) or 32 KB (ATmega328) of which 2 KB used by bootloaderSRAM: 1 KB (ATmega168) or 2 KB (ATmega328)EEPROM: 512 bytes (ATmega168) or 1 KB (ATmega328)Clock Speed: 16 MHzDimension: 0.73" x 1.70" PowerThe Arduino Nano can be powered via the Mini-B USB connection, 6-20V unregulated external power supply (pin 30), or 5V regulated externalpower supply (pin 27). The power source is automatically selected to the highest voltage source. The FTDI FT232RL chip on the Nano is only powered if the board is being powered over USB. As a result, when running on external (non-USB) power, the 3.3V output (which is supplied by the FTDI chip) is not available and the RX and TX LEDs will flicker if digital pins 0 or 1 are high. MemoryThe ATmega168 has 16 KB of flash memory for storing code (of which 2KB is used for the bootloader); the ATmega328 has 32 KB, (also with 2 KBused for the bootloader). The ATmega168 has 1 KB of SRAM and 512 bytesof EEPROM (which can be read and written with the EEPROM library); the ATmega328 has 2 KB of SRAM and 1 KB of EEPROM.
