 Arduino Nano V3.0

 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. The Nano was designed and is being produced by Gravitech.
Schematic and Design
Arduino Nano 3.0 (ATmega328): schematicEagle files.
Arduino Nano 2.3 (ATmega168): manual (pdf), Eagle filesNote: since the free version of Eagle does not handle more than 2 layers, and this version of the Nano is 4 layers, it is published here unrouted, so users can open and use it in the free version of Eagle.
Specifications:
Microcontroller Atmel ATmega168 or 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 16 KB (ATmega168) or 32 KB (ATmega328) of which 2 KB used by bootloader
SRAM 1 KB (ATmega168) or 2 KB (ATmega328)
EEPROM 512 bytes (ATmega168) or 1 KB (ATmega328)
Clock Speed 16 MHz
Dimensions 0.73" x 1.70"

 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.
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 TXLEDs will flicker if digital pins 0 or 1 are high.

 Memory

The ATmega168 has 16 KB of flash memory for storing code (of which 2 KB is used for the bootloader); the ATmega328has 32 KB, (also with 2 KB used for the bootloader). The ATmega168 has 1 KB of SRAM and 512 bytes of EEPROM (which can be read and written with the EEPROM library); the ATmega328 has 2 KB of SRAM and 1 KB of EEPROM.

Arduino Nano是一塊基於開放程式碼的超小Simple I/O平臺,與之前的USB版Arduino Diecimila相比較,Arduino Nano在體積上占很大優勢,Arduino即可以用來開發出需要獨立運行,並且具有互動效果的電子用品;也可以用來開發出與電腦相連接,同Flash,Processing,等軟體一同合作完成的互動作品。
 
Arduino Nano的技術參數: 
  1. 14個數位輸入/輸出埠TX,RX,D2~D13,
  2. 8個模擬輸入埠A0~A7
  3. 1對TTL電平串口收發埠RX/TX
  4. 6個PWM埠,D3, D5, D6, D9, D10, D11
  5.  採用Atmel Atmega328P-AU單片機
  6.  支持USB下載及供電
  7.  支持外接5V~12V直流電源供電
  8.  支援9V電池供電
  9.  支持ISP下載
  10.  三種供電方式:USB,VIN,外部5V輸入
