Transistor NPN C1815 C 1815 general purpose transistor Arduino

It has similar structure with Arduino Diecimila/Duemilanove, but different size. 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 operation frequency in 12Mhz, yields stable result of a data interchange (for correct installation of drivers on the computer follow the instruction). Nano V3, can be powered via microUSB-port (up to 500mA). External power supply 6-12V unregulated to output VIN, or 5V external power source to a regulate output of 5V. The power supply is automatically selected with the maximum voltage value.
* This Nano ATmega168 have PinOut for V3, not V2.
