Description Overview The Arduino Nano is a small, complete, and breadboard-friendly board based on the ATmega328 (Arduino Nano 3.x) orATmega168 (Arduino Nano 2.x). 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. 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) Specifications: Microcontroller Atmel ATmega328 Operating Voltage (logic level) 5 V Input Voltage (recommended) 7-12 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″ Features: Automatic reset during program download Power OK blue LED on the bottom Green (TX), red (RX) and orange (L) LED 5V to AREF jumper Auto sensing/switching power input Small mini-B USB for programming and serial monitor (cable not included) ICSP header for direct program download Power OK blue LED on the bottom Standard 0.1” spacing DIP (breadboard friendly) Manual reset switch The Arduino Nano can be powered via the mini-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. package include Package Includes: 1x Arduino Nano v3.0 1x Free USB Cable Links: Detailed Information: http://arduino.cc/en/Main/arduinoBoardNano Schematics: http://arduino.cc/en/uploads/Main/ArduinoNano30Schematic.pdf
