Nano V3.0 ATmega168 CH340G Mini USB Board: 16MHz, 5V Microcontroller with USB-to-UART

New version-Nano V3 built on the ATmega168 minicontroller (16MHz) has a small size and can be used with a model board for solderless wiring (breadboard). It has a similar structure to Arduino Diecimila / Duemilanove, but the size is different. In order to reduce the size, components are mounted on both sides of the PCB.

This board uses CH340G chip as converter UART-USB. Chip CH340G-is a budget solution. Under the working frequency of 12Mhz, you can get stable data exchange results (install the driver correctly on the computer according to the instructions).

Nano V3 can be powered via the miniUSB port (up to 500mA). External power supply 6-12V unregulated output VIN or 5V external power supply regulated output 5V. The power supply automatically selects the maximum voltage value.

*This nano ATmega168 has PinOut for V3 instead of V2.
