<description>&lt;b&gt;Arduino Nano V3.0&lt;/b&gt;&lt;br&gt;&lt;br&gt;

&lt;b&gt;Overview:&lt;/b&gt;&lt;br&gt;

The Arduino Nano is a small, complete, and breadboard-friendly board based on the ATmega328 (Arduino Nano 3.x) or ATmega168 (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.&lt;br&gt;
The Nano was designed and is being produced by Gravitech.&lt;br&gt;&lt;br&gt;

&lt;/table&gt;
&lt;br&gt;&lt;br&gt;

&lt;b&gt;Power:&lt;/b&gt;&lt;br&gt;

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).&lt;br&gt;
The power source is automatically selected to the highest voltage source.&lt;br&gt;&lt;br&gt;

&lt;b&gt;Memory:&lt;/b&gt;&lt;br&gt;

The ATmega168 has 16 KB of flash memory for storing code (of which 2 KB is used for the bootloader); the ATmega328 has 32 KB, (also with 2 KB used for the bootloader).&lt;br&gt;
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.&lt;br&gt;&lt;br&gt;

&lt;b&gt;Input and Output:&lt;/b&gt;&lt;br&gt;

Each of the 14 digital pins on the Nano can be used as an input or output, using pinMode(), digitalWrite(), and digitalRead() functions.&lt;br&gt;
They operate at 5 volts.&lt;br&gt;
Each pin can provide or receive a maximum of 40 mA and has an internal pull-up resistor (disconnected by default) of 20-50 kOhms. In addition, some pins have specialized functions.&lt;br&gt;&lt;br&gt;

<description>&lt;b&gt;Arduino Nano V3.0&lt;/b&gt;&lt;br&gt;&lt;br&gt;

&lt;b&gt;Overview:&lt;/b&gt;&lt;br&gt;

&lt;p&gt;The Arduino Nano is a small, complete, and breadboard-friendly board based on the ATmega328 (Arduino Nano 3.x) or ATmega168 (Arduino Nano 2.x). &lt;br&gt;It has more or less the same functionality of the Arduino Duemilanove, but in a different package.&lt;br&gt;
It lacks only a DC power jack, and works with a Mini-B USB cable instead of a standard one.&lt;br&gt;
The Nano was designed and is being produced by Gravitech.&lt;/p&gt;&lt;br&gt;

&lt;b&gt;Specifications:&lt;/b&gt;
&lt;table border="1" style="width:auto"&gt;

    &lt;td&gt;14 (of which 6 provide PWM output)&lt;/td&gt;

    &lt;td&gt;SRAM&lt;/td&gt;
    &lt;td&gt;1 KB (ATmega168) or 2 KB (ATmega328)&lt;/td&gt;
