Clone Arduino & driver chip CH340, CH340G, CH341
Category : RESOURCES
The CH340/CH341 chip is used by a number of Arduino compatible cards to provide USB connectivity.
Many operating systems do not recognize these chip natively because they lack the drivers and consequently we have an error due to lack of drivers.
The lack of this driver does not allow you to communicate with the hardware platforms and to use the Arduino development software.
No panic, driver installation is very easy!
The driver must be downloaded from the official (Chinese) website.
Once the unzip of the package has been executed, it is possible to proceed with the update of the driver for the device CH340/CH341 and equivalent (download driver only for your OS):
WINDOWS 32/64bit (version: 3.4 – 2016/09/27)
Drivers in the Windows OS are missing, you need to download and install them.
LINUX 32/64bit (version: 1.5 – 2018/03/18)
The drivers are integrated into different Linux distributions. If the device is not recognized, download the Linux CH340/CH341 driver.
MAC OS 32/64bit (version: 1.5 – 2018/07/05)
This driver is for MacOS Sierra/High Sierra. Do not install the drivers for the Mojave, because it seems that the latest versions are equipped with the built CH340/CH341 support.
Installation
• Unplug any CH34* devices.
• Unload the old drivers if running:
• sudo kext unload /Library/Extensions/usbserial.kext
• sudo kext unload /System/Library/Extensions/usb.kext
• Remove the old driver by issuing one of the following commands (depending on your installation):
• sudo rm -rf /System/Library/Extensions/usb.kext
• sudo rm -rf /Library/Extensions/usbserial.kext
• Double-click on the CH34x_Install_V1.3.pkg file and install (no need to reboot)
• Instead of rebooting, you can force quit Installer after it completes.
• Load the new driver:
• sudo kextload /Library/Extensions/usbserial.kext
• Plug in your device. It should now be listed under the /dev directory. Examples:
• /dev/cu.wchusbserial1410
• /dev/cu.wchusbserial1420
ANDROID (version: 1.5 – 2018/03/18)
Enjoy!
The origional Arduino NANO boards are getting very difficult to find these days and you may find yourself in posession of one of the newer Arduino compatiable NANOs with teh CH340G chip on the bottom (instead of the origional FTDI chip). Here is a great instructable that explains how to install the drivers and the differences.http://www.instructables.com/id/Arduino-Nano-USB-Not-Recognizing-Fix/
Introduction: Arduino Nano USB Not Recognizing (Fix).
Arduino Nano USB Not Recognizing (Fix).
Step 1: Arduino Nano Clones
Unfortunately an original Arduino Nano could cost you more plus shipping so it makes sense to search for an alternative source. There are also some chinese clones that are around five times cheaper, even with worldwide shipping.
But wait! There’s always a reason why a clone of something is cheaper than the original product. In this case there can be two pitfalls you need to know about.
Step 2: Original FTDI for Data Communication
Sometimes the FTDI chip which makes the USB communication possible is a counterfeit. This could cause problems when you install the official FTDI drivers and they just refuse to work.Usually there is no bootloader on the microcontroller. You need to upload it yourself and that means you need to have an appropriate programmer on hand.
Step 3: The Bad Part About Cheap Chinese Clones
So what makes this clone cheaper than the others? Well, most probably two things:
1.The headers are not installed.
Ch340g Driver Windows 10 Dell
2.It uses a different chip (CH340G) for serial-USB communication than the others.
The different serial chip on the other hand was something I was a little bit worried about but I’ve found my fears to be baseless. When I connected the board to the computer with a miniUSB cable it was instantly recognised by Windows as a virtual serial port.
Step 4: USB Not Recognizing
Step 5: Download Driver for CH340/CH341
The chipset used for USB-to-serial is CH340/CH341, drivers for which can be downloaded here.

Step 6: Unzip & Install the Driver
Step 7:
Install Ch340g Driver
DONE!!
