The Arduino Nano is a small, complete, and breadboard-friendly board based on the ATmega328 (Arduino Nano 3.0). It has more or less the same functionality of the Arduino Duemilanove, but in a different package. It lacks only a DC power jack, and works with a Mini-B USB cable instead of a standard one. <br>

== Features ==
 
Microcontroller: Atmel ATmega328
 
Operating Voltage (logic level): 5 V
 
Input Voltage (limits): 6-20 V
 
Digital I/O Pins:14 (of which 6 provide PWM output)
 
Analog Input Pins: 8
 
DC Current per I/O Pin: 40 mA
 
Flash Memory: 32 KB (ATmega328) of which 2 KB used by bootloader
 
SRAM:2 KB (ATmega328)
 
EEPROM:1 KB (ATmega328)
 
Clock Speed: 16 MHz
 
Dimensions: 0.73" x 1.70"
 
Length: 45 mm
 
Width: 18 mm
 
== Power==
 
The Arduino Nano can be powered via the Mini-B USB connection, 6-20V unregulated external power supply (pin 30), or 5V regulated external power supply (pin 27). The power source is automatically selected to the highest voltage source.<br>
 
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.<br>
