Driver For Ch340/ch341 Mac

3d print software for mac. The best USB to Serial drivers for macOS Drivers for CP2102 / CH340 / CH341 / PL2303 Devices. Program your Arduino, ESP8266 within a couple of minutes, control your Cisco, or download your GPS tracker, our drivers enable it.

Recently I tried connecting my newly purchased clone version of the Arduino UNO with the MacBook OS X Yosemite. It turns outs that, nothing gonna detect my serial port.

This is because most of the clone versions are using a different chip for USB-to-Serial communication namely CH340/CH341 instead of ATmega16U2. After hours of work and digging throughout the Internet, I found these drivers for CH341/CH340 is working as expected. Here how you do it; Download the drivers and install relevant setup. This package includes, drivers for linux, mac os x and windows. One more additional step for Mac OS X users. Disable the kext signing security setting with this command.

Sudo nvram boot-args='kext-dev-mode=1' How to test it; on the terminal type; ls /dev/tty* you should see something like '/dev/tty.wchusbserial1410'. In addition, if you open up your Ardunio IDE then goto Tools->Port. You should see something similar to below.

If you are like me and ordered a cheap arduino nano clone from a chinese website like aliexpress or banggood, chances are that they come with the cheaper CH340 USB to Serial chip. This is a cheap chip that manufacturers exploit to make the clone a lot cheaper.

This can also be a downside. For me, being a mac user, I had a real hard time finding drivers etc for it. In the end I found some drivers, which were pretty good and I finally could get a blink sketch uploaded. I now want to share my experience for future buyers so you can get it working a lot faster.

If everything is done correctly and there were no errors appearing. You should be able to restart your arduino IDE and see the port. For my mac it is usually like above in the picture but sometimes it changes.

You will also notice that once in a while (maybe 1 time of 3) you will get errors when uploading but you do not have to care, the code will usually upload either way. I hope this tutorial helped you and remember that the CH340 chip is a bit complicated and it may also be used in other cheap arduino board clones. Thanks for reading and once again, I hope it helped you.

As a linux user (Ubuntu / Linux Mint 17) I had difficulties with the cheap Nano with the CH340G chip getting it to work properly - the upload of any code didn't work at all. Of course I had installed the Arduino IDE (apt-get install arduino) but was not able to program the Arduino nano. Then I found in a german web article that from time to time you have to reinstall the IDE after a system update of the kernel, so that the serial USB interface works again.

How to put windows on virtualbox for mac. I didn't do it but my Nano started to blink when connected to the USB port so I thought it couldn't be out of order and should work anyhow. After connecting it to USB in the /dev folder you should find a file called ttyUSB0 or ttyUSB1 or so.

In my /dev folder I had found it. So I started again, setting the Arduino IDE platform tool menu 'Tools' and 'Board' to 'Arduino Nano w/ATmega328' (in my case) and 'Tools' 'Serial port' to '/dev/ttyUSB1' (in my case). Now, the code from the 'Blink' example in the IDE could be uploaded to the Nano board as it should be and the LED started to blink.
