How to install CH340 driver for windows 11

Using Arduino Avrdude, stk500, Bootloader issues
1

Hi all, I'm new here, pls help me. I tried to installing the ch340 driver for windows 11. I don't know why the ch340 didn't show up after I'm installing the driver. Already tried to change the cable data, restarting my computer, still didn't work. I'm using ESP8266MOD.

Hi @hazzard123. It appears your ESP8266 board might use a Silicon Labs CP210x USB chip instead of the WCH CH340 chip. Although the WCH CH340 chip is very common, it is only one of several USB to serial chips you might find used on the various Arduino boards. If your ESP826 board does use the Silicon Labs CP210x USB chip then it is normal and expected that you wouldn't see it listed as a CH340 in the Windows Device manager.

If that COM5 port is indeed your ESP8266 board (instead of it being from some other random device attached to your computer, which is also possible), then it appears everything is perfectly fine.

Are you experiencing some problem when using your ESP8266 board in Arduino IDE? If so, please provide a detailed explanation of the problem, including:

  • What did you do?
  • What were the results you expected from doing that thing?
  • What were the results you observed that did not match your expectations?

Make sure to include the full and exact text of any error or warning messages you might have encountered.

I think I know the answer. AZdelivery (I know that vendor, is one of my favourite ones!) sells some ESP32 (not ESP8266!) with either CH340 or CP2102, so I'm pretty sure you have the latter, so you don't need any CH340 driver.
In fact, if you search your board with a magnifying glass I think you'll see this:

And I'm quite sure Windows 11 already downloaded the driver for you.

PS: always provide full description of your board, there are many ESP boards from various manufacturers, so a detailed an sharp picture of the board and, if possible, also a direct link to the exact item you bought, could better help us to help you.

PS2: that has nothing to do with IDE 1.x, anyway...
