The Viduino Nano CH340G without USB Cable chipboard is based on the famous Arduino platform and does all the functions of Uno, but with a smaller footprint.

The Nano board compatible with arduino equips a low-cost USB-Serial Chip that makes it reliable and suitable for projects based around arduino. The Nano microcontroller board is a small, complete, and breadboard-friendly board based on the ATmega328 (Arduino Nano R3). 

The CH340 Nano microcontroller board can be powered via the mini-USB connection, 6-20V unregulated external power supply (pin 30), or 5V regulated external power supply (pin 27). The power source is automatically selected to the highest voltage source.
