The Arduino Nano is a small, complete, and breadboard-friendly board based on the ATmega328. It has more or less the same functionality of the Arduino Uno, 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. It includes an ch314a USB to Serial chip so only needs a USB cable (supplied) in order to program it. Cable Included. CH314A driver Specifications: Atmel ATmega328 MCU Operating Voltage (logic level) 5 V Input Voltage (recommended) 7-12 V 14 Digital I/O Pins (of which 6 provide PWM output) 8 Analog Input Pins DC Current per I/O Pin 40 mA 32Kb Flash Memory (of which 2KB used by bootloader) 1 KB SRAM 512 bytes EEPROM 16MHz Clock Speed Dimensions 0.7 inch x 1.7 inch (18mm x 43mm) Documents Arduino Nano Product Page
