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. Windows () • Download the • 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.

Firmware working with VCDS 805 english version. Firstly we must supply the interface with a voltage of 12 volts, for this we solder 2 wire on 7805 regulator.

Macintosh () (V1.3) 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. I can personally not test on MacOS and can not vouch for the above drivers at github, but there you go.

See 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) Linux () 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 (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 in case they have issued an update since I wrote this page. Secondly 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 -r filename`.
