The CH340 chip is used by a number of Arduino compatible boards to provide USB connectivity, you may need to install a driver, don't panic, it's easier than falling off a log, and much less painful.
Open-source electronic prototyping platform enabling users to create interactive electronic objects. Since march 2015, the arduino ide has been downloaded so many times. (impressive!) no longer just for arduino and genuino boards, hundreds of companies around the world are using the ide to program their devices, including compatibles, clones, and even counterfeits. Download Driver for the Mac OS X version, named 2.2.18 (32bit) Open the driver file which you just download, and double click FTDIUSBSerialDriver104105106107.mpkg After double click, you will see an installer window.
- Manager for Linux.
- I just posted Arduino 0021 to the download page. It's a quick release to fix the problems with analogWrite (PWM) on pins 9 and 10 on the Arduino Uno. This release also includes Linux (32-bit) support for the Uno and Mega 2560 (as well as the rest of the Arduino boards). The RXTX library was.
Windows
(Manufacturer's Chinese Info Link)
- Download the Windows CH340 Driver
- Unzip the file
- Run the installer which you unzipped
- In the Arduino IDE when the CH340 is connected you will see a COM Port in the Tools > Serial Port menu, the COM number for your device may vary depending on your system.
Older Windows Driver Version and Instructions
- Download the Windows CH340 Driver
- Unzip the folder.
- If you are running a 64Bit Windows: – run the SETUP_64.EXE installer.
- If you are running a 32Bit Windows: – run the SETUP_32.EXE installer.
- If you don't know, try the 64 bit and if it doesn't work, the 32 bit.
- In the Arduino IDE when the CH340 is connected you will see a COM Port in the Tools > Serial Port menu, the COM number for your device may vary depending on your system.
Macintosh
(Manufacturer's Chinese Info Link)
The following github has up to day pkg files for 1.3, 1.4 and 1.5 at time of writing, thanks to Joshua Wallis for bringing this to my attention…
Direct Download Links (from the github repo above):
See the github link above for installation instructions if you need them.
Previous macinstosh downloads if the above doesn't work for you…
(V1.3) Download the CH340 Macintosh Signed Driver for Mavericks (10.9), Yosemite (10.10) and El Capitan (10.11) and Sierra (10.12)
Inside the zip file you will find a PDF and a 'pkg' file, short version, double click the pkg file, the PDF has some extra information.
OSX Sierra (10.12) Note
A kindly user, Maarten Segers reports Download far cry 4 for mac.
FYI, the driver documented here WILL crash on OSX Sierra.
I can personally not test on MacOS and can not vouch for the above drivers at github, but there you go.
See uninstalling information at the bottom of the page if the driver causes problems for you.
Here is an older version of the Mac driver, NOT FOR 10.12 Sierra
(V1.0) Download the CH340 Macintosh Signed Driver for Mavericks (10.9), Yosemite (10.10) and El Capitan (10.11) Adobe creative cloud app download for mac.
Linux
(Manufacturer's Chinese Info Link)
Drivers are almost certainly built into your Linux kernel already and it will probably just work as soon as you plug it in. If not you can download the Linux CH340 Driver (but I'd recommend just upgrading your Linux install so that you get the 'built in' one).
Uninstalling From Macinstosh
A couple of Mac users have said 'the driver crashes my mac Sierra how do I uninstall'.
Firstly regards the crash make sure you installed the 1.3 version of the driver, not the old one. You could download it directly from the Manufacturers Website in case they have issued an update since I wrote this page.
Secondly a quick google search reveals that this is how you uninstall:
- Open a terminal and type:
cd /Library/Extensions/ - Verify that the .kext file is present:
ls | grep usbserial.kext - Output should be:
usbserial.kext - Then type:
sudo rm -R usbserial.kext - Verify that the .kext file has been removed:
ls | grep usbserial.kext - Output should be empty.
- After you should remove the files stored in receipts folder:
cd /private/var/db/receipts/ - Find the enties:
ls | grep usbserial* - Output should be:
codebender.cc.ch34xinstaller.usbserial.pkg.bom codebender.cc.ch34xinstaller.usbserial.pkg.plist - Remove each one of the files of the above list:
sudo rm -rfilename`
Install the Arduino Software (IDE) on Windows PCs
This document explains how to install the Arduino Software (IDE) on Windows machines

Download the Arduino Software (IDE)
Get the latest version from the download page. You can choose between the Installer (.exe) and the Zip packages. We suggest you use the first one that installs directly everything you need to use the Arduino Software (IDE), including the drivers. With the Zip package you need to install the drivers manually. The Zip file is also useful if you want to create a portable installation.
