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.

Make use of available links in order to usb-serial ch341a an appropriate driver, click on those links to start uploading. This option requires basic OS understanding. Oct 30, 2019 I've read the other threads suggesting to download the CH341SERMACZIP driver in order to get the newer Mac's with USB C to work with the IDE. Maybe its just me, but i have some 'concern' about the CH340/CH341 USB to serial MAC OS driver given it seems like non-official arduino software(?). My concern being around system security. PL2303SA provides a convenient simple solution for connecting an RS232-like full-duplex asynchronous serial device (TX-RX only) to any Universal Serial Bus (USB) capable host. PL2303SA highly compatible drivers could simulate the traditional COM port on most operating systems allowing the existing applications based on COM port (using TX-RX.
Windows

- 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.

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 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 -r
filename
