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.

Program your Arduino, ESP8266 within a couple of minutes, control your Cisco, or download your GPS tracker, our drivers enable it. For Mac OS X users with supported products, if a driver is not provided by the operating system, they must be downloaded and installed. For Linux/Unix users, support varies widely by product, kernel version, and OS distribution. Click a product category below for driver downloads and installation instructions. Ongoing macOS FTDI driver issues plague many users connecting the Arduino IDE to boards that use an FTDI chip. Since our boards use an FTDI chip for USB-to-serial communication, we have witnessed some of these issues when working with our boards using Mac and macOS.


Windows

(Manufacturer’s Chinese Info Link)

  1. Download the Windows CH340 Driver
  2. Unzip the file
  3. Run the installer which you unzipped
  4. 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

  1. Download the Windows CH340 Driver
  2. Unzip the folder.
  3. If you are running a 64Bit Windows: – run the SETUP_64.EXE installer.
  4. If you are running a 32Bit Windows: – run the SETUP_32.EXE installer.
  5. If you don’t know, try the 64 bit and if it doesn’t work, the 32 bit.
  6. 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.
Serial Driver For Mac

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

FYI, the driver documented here WILL crash on OSX Sierra.

Make sure to use this one instead: https://github.com/MPParsley/ch340g-ch34g-ch34x-mac-os-x-driver

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)Hal 9000 windows 10 theme.

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:

Ftdi Driver For Mac

  1. Open a terminal and type: cd /Library/Extensions/
  2. Verify that the .kext file is present: ls grep usbserial.kext
  3. Output should be: usbserial.kext
  4. Then type: sudo rm -R usbserial.kext
  5. Verify that the .kext file has been removed: ls grep usbserial.kext
  6. Output should be empty.
  7. After you should remove the files stored in receipts folder: cd /private/var/db/receipts/
  8. Find the enties: ls grep usbserial*
  9. Output should be: codebender.cc.ch34xinstaller.usbserial.pkg.bom codebender.cc.ch34xinstaller.usbserial.pkg.plist
  10. Remove each one of the files of the above list: sudo rm -r filename`

PLEASE NOTE - When updating drivers, refer to the following document: AN_107 - Advanced Driver Options

New drivers are now available to support the FT4222H - for D2XX drivers please click here.

Pl2303 Mac Driver

Drivers are available which allow FTDI devices to work with the following operating systems:
Windows CertifiedOthersLegacy
Windows 10 (32/64)LinuxWindows Vista (32/64)
Windows 8.1 (32/64)MAC OSXWindows XP (32/64)

Support for WinCE
FTDI drivers are available for Windows CE 4.2-5.2, 6.0/7.0 and 2013.

Support for older versions of Windows Desktop

NOTE: Microsoft have ended support for certifying XP and VISTA through their WHCK test program. From revision 2.12.24 with Device Guard Support, the driver will not load on XP or VISTA.

Fallout 1 and 2 free. Differences in Driver API

For most of these operating systems two types of driver are available: Virtual COM Port (VCP) drivers and direct (D2XX) drivers. The VCP driver emulates a standard PC serial port such that the USB device may be communicated with as a standard RS232 device. The D2XX driver allows direct access to a USB device via a DLL interface.

To locate the drivers you want to install for a device, select which of the driver types you wish to use (VCPor D2XX) and then locate the appropriate operating systems. With the exception of Windows 98 and Windows ME, all devices are supported in each driver package.

If a VCP driver is required for Android please refer to the following application note: TN 132 Adding FTDI Devices VCP Driver Support to Android

D3XX

D3XX drivers are only suitable for FTDI's Superspeed USB bridge services (e.g. FT60x series).
