Hi,
I have recently purchased the board: UNO+WiFi R3 ATmega328P+ESP8266 Board 32Mb Memory USB-TTL CH340G Compatible from banggood website.

I have downloaded the USB CH340G drivers and installed. I have changed switch settings to Switch Position: 3,4 ON rest all are OFF, so that i can use as simple UNO ATmega328. In the Arduino design also setup the serial port and board type as Arduino UNO. By using simple builtin example Blink, Sketch gets compiled but unable to Upload sketch.

Kindly help me in setting up the environment to upload sketch by Arduino setup (Windows Desktop) for the above board.

Thanking you in advance.

Assuming you are using Windows....
Open the Device Manager and expand "Ports (COM & LPT)". does the USB port for your CH340 appear there?
If it does, then that is the port you need to select in the tools tab.

In the Device Manager, if there is a yellow "!" next to the CH340 device, then you have a bad driver or a bad CH340 chip.
