as official Arduino, so please download drive for CH340 from

In Windows system, you just need to click “ CH341SER_WINDOWS.EXE ”,Then
follow the system prompts to install.
After the installation is complete, when you connect the nano board to your
computer, open the “Device Manager” and you can see that the CH340 driver
has been installed successfully and the port number is displayed.
