![]() ![]() In Arduino IDE – Board = Nano, Processor = ATmega168. * This Nano ATmega168 have PinOut for V3, not V2. The power supply is automatically selected with the maximum voltage value. The main difference between them is in microcontroller: Nano v.2 uses Atmega168, whereas Nano v.3 has Atmega238. External power supply 6-12V unregulated to output VIN, or 5V external power source to a regulate output of 5V. Note: Arduino Nano comes in various options, however, the most popular are Nano v.2 and Nano v.3. On board have fuser for 500mA for save from SUB-port. Nano V3, can be powered via microUSB-port (up to 500mA). With an operation frequency in 12Mhz, yields stable result of a data interchange (for correct installation of drivers on the computer follow the instruction). The board uses a chip CH340G as converter UART-USB. To reduce the size, components are mounted on both sides of the PCB. It has similar structure with Arduino Diecimila/Duemilanove, but different size. Nano V3 constructed on the ATmega168 microcontroller (16MHz) has the small size and can be used together with model boards for solderless wiring (breadboard).
