Nano V3 constructed on the ATmega328 microcontroller (16MHz) has a small size and can be used together with model boards for solderless wiring (breadboard). It has a similar structure with Arduino Diecimila/Duemilanove, but different sizes.
To reduce the size, components are mounted on both sides of the PCB. The board uses a chip CH340G as converter UART-USB. Chip CH340G - is a budget solution.
With an operating frequency in 12Mhz, yields a stable result of a data interchange (for correct installation of drivers on the computer follow the instruction).
Nano V3 can be powered via micro-USB-port (up to 500mA). Onboard have fuser for 500mA for save from SUB-port.
External power supply 6-12V unregulated to output VIN, or 5V external power source to a regulated output of 5V.
The power supply is automatically selected with the maximum voltage value. Pin headers not soldered. Pin headers inset. In Arduino IDE - Board = Nano, Processor = ATmega328.
Microcontroller: Atmel ATmega328P; Pin headers not soldered. Pin headers inset.
Operating Voltage (logic level): 5V Input Voltage (recommended): 7V ~ 12V Input Voltage (limits): 6V ~ 20 V
Power In (pin VIN):6-12V, Power Out:5V-800mA 3.3V-800mA, Power to USB-port:5V (500mA maximum)
Flash Memory: 32KB (ATmega328) (of which 2 KB used by bootloader) SRAM: 2KB (ATmega328) EEPROM: 1KB (ATmega328) Clock Speed: 16MHz USB to Serial Converter: CH340
