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.
How to install Driver for Arduino in Mac OS. Download Driver for MAC and right version for your PC. Open the file folder you just downloaded and double click the FTDIUSBSerialDriverv2218.dmg and press continue. ← How to install Arduino Driver for UNO R3. From the arduino.cc website, we'll go to Learning, Get Started. This page contains download and installation instructions for Windows, Mac OSX, or Linux. From here, I'll choose the Mac OSX. Next, I will go to the downloads page and start my download. While that is downloading, I will go back to the getting started page for Mac OS 10. The Uno board and version 1.0 of Arduino Software (IDE) were the reference versions of Arduino, now evolved to newer releases. The Uno board is the first in a series of USB Arduino boards, and the reference model for the Arduino platform; for an extensive list of current, past or outdated boards see the Arduino.
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.

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…

See the github link above for installation instructions if you need them.
Previous macinstosh downloads if the above doesn’t work for you…
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).
Arduino Uno Driver For Mac Os Seagate
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 -r
filename
