ch341ser usb driver driver pre install falure

NOTE: Some users notified that Arduino clones which use CH340G chip are not working properly on USB 3.0.

Restart your computer after installation (Important).

Click Install, once the driver installed it says “Driver Install Success”.

Now it will prompt you with 3 options: Install, uninstall and help.

It will ask for administrator permissions, click YES.

Download the CH340G drive from the given link.

You can download the CH340G driver for these kinds of Arduino boards: Click Here How to install CH340G Driver to windows Computer: You can also find this CH340G chip even on Arduino nano clones as illustrated below: Arduino Nano with CH340G chip

You have to install CH340G driver to your computer only then your computer will recognize the device and able to upload sketches. You can see this on cheap Chinese Arduino clones this chip will not be detected neither by your computer nor the IDE. This is called CH340G USB to serial converter chip. As you can see there is a difference in the USB to serial converter chip. The above Arduino board is SMD type this board has exactly same specification as genuine Arduino UNO. Now let’s inspect another Arduino board clone, which doesn’t utilize ATmega16U2 for USB to serial conversion. The clones which utilize ATmega16U2 as USB to serial converter for the microcontroller won’t have any issues with detection. Here is an Arduino UNO clone with ATmega16U2 controller which is used as USB to serial converter, the same converter is also utilized on genuine Arduino boards. To find out why the Arduino boards are not detected, let’s inspect the Arduino board’s USB to serial converter chip.Ī USB to serial converter module is utilized on all Arduino boards to uploading sketches to the microcontroller and also for serial communication between the computer and the main microcontroller.

Your IDE will not show the connected Arduino board and you device manager will say “unknown USB device”, when you try to fix with windows tools you will still end up not fixing the issue. This is a very common issue faced by most Arduino beginners and sometimes even who has intermediate experience with Arduino. Why your Arduino is not detected by your computer? Here we will discuss the possible problems why your Arduino board is not detected or why you couldn’t upload the sketch/code and we will see the recommended solutions. You landed on this page because you could not upload your sketch to Arduino or it is not even detected by your trusty computer.

Solutions for not detection of Arduino boards.

Why your Arduino is not detected by your computer?.

In this post we are going to solve Arduino software and driver related issues which are driving some beginners crazy and we will also address some of the problems related to Arduino hardware.
