Arduino Nano v3.0 Clone without Cable
Overview : The Arduino Nano v3.0 clone is a small, complete, and breadboard-friendly board based on the . 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.
|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 () of which 2 KB used by bootloader|
|SRAM||2 KB ()|
|EEPROM||1 KB ()|
|Dimensions||0.73" x 1.70"|
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 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 will flicker if digital pins 0 or 1 are high.
The has 32 KB, (of which 2 KB used for the bootloader). The has 2 KB of SRAM and 1 KB of EEPROM (which can be read and written with the EEPROM Library).
