CH340G Replace FT232RL,so pls. use the driver from this link:https://github.com/emakefun/emakefun-nano-kit

The Upgraded Emakefun Nano is a small, complete, breadboard-friendly and high quality board based on the Atmega328P-AU MCU. Adopting Immersion Gold Technology. Support ISP download, USB download and USB Power

No Soldering needed. The Upgraded Emakefun Nano improved the design of PCB to solve the issue that the pins of Nano can't fit to breadboard perfectly. When you use our upgraded Nano, you will find the Pins are aligned nicely with the holes of breadborad

Nano's got the breadboard-ability of the Boarduino and the Mini+USB with smaller footprint than either, so users have more breadboard space. We use high quality PCB original material and iproved produce technology to make sure every board has smooth edge and more reliable quality

It lacks only a DC power jack, and works with a Mini-B USB cable instead of a standard one, 6-20V unregulated external power supply (pin 30), or 5V regulated external power supply (pin 27). Follow this link:https://github.com/emakefun/emakefun-nano-kit/blob/master/Resume_Arduino_BootLoader.pdf, you can easily solve the problem that the nano board cannot download the program when it is connected to the computer.
