Things are promising if you find a similar result. Using Terminal, verify that the device is recognized by listing the contents of the /dev directory and looking for cu.wchusbserial1420 or cu.wchusbserial1410 in the output: ls /devįor example, I found cu.wchusbserial1420 in the output when I connected my Robotdyn Uno. Next, plug your Arduino clone into a free USB port.
When the install completes, reboot your machine. The first one runs long, so take care when copying and pasting.) To begin, install the drivers with brew cask: brew tap mengbo/ch340g-ch34g-ch34x-mac-os-x-driver īrew cask install wch-ch34x-usb-serial-driver Verify its presence and version info by executing brew -version in Terminal. Prerequisite: ensure brew installed on your Mac.
I had no problem getting a Robotdyn Arduino Uno as well as another cheap clone running on a Mac with High Sierra. These drivers are signed by the OEM so its no longer necessary to disable Mac’s System Integrity Protection (SIP) feature. He has bundled the manufacturer’s latest Sierra-compatible CH340/CH34G/CH34X drivers for installation with brew cask. The easy installation method covered in this post comes courtesy of one Adrian Mihalko. Most sellers on “China deal sites” like are up-front about these chips and include “CH340” in their product titles and descriptions, though the implications of this design modification are not alway understood by purchasers.
Many clones are not recognized “out of the box” because they implement their USB to serial interface with a CH340 chip designed by China’s WCH ( ) instead of the more costly FTDI chip found in genuine Arduinos. This post details how to get cheap Arduino clones working with MacOS Sierra so you can upload sketches to them.
