• I am using a Windows 10 laptop. Behind the nodemcu it says that download CH340G driver.
  • I already had arduino ide and the esp libraries were already installed because i was using a esp8266 01 device before.
  • I bought a Nodemcu i downloaded the driver for it CH340G driver.
  • When i install the driver it says that The drive is successfully pre-installed in advance!
  • When I plug my Nodemcu to my computer with a new cable blue lights come from the board and it stops. And windows doesn't make a sound which indicates that it sees the device.
  • I don't think the nodemcu is the problem. How do i fix this?
  • so are you are not able to see the nodemcu in arduino

  • so what's the problem if u can see it in Arduino then you can upload code to the node muc please tell me what you want .

  • If Windows doesn't make a sound then it doesn't see the device being plugged in. Are you sure you're usb cable has data wires in it?

Read through https://stackoverflow.com/questions/43007501/nodemcu-not-detected-by-computer#:~:text=I%20had%20to%20install%20the,Afterwards%2C%20it%20worked.&text=For%20future%20people%20with%20this,and%20it%20wouldn't%20detect. and also search few ways to remove oxidation from pins like using autosol (I have never used it ) . Try uploading code through FTDI modules or just get it replaced.
