CH340 serial chip Drivers for Linux, Mac, and Windows all in one place

A One-Stop driver repo for the popular serial chip used on cheap Chinese Arduino clones.

The CH340G chip is a very popular USB to Serial chip used in Arduino clones because of its low cost. The OEM of this chip is Jiangsu Qinheng Co., Ltd. in the Nanjing Software Valley of China according to SparkFun who builds products that incorporate it.

Unfortunately, their website, being entirely in Chinese, makes many people nervous. For this reason, there have been many people who have tried to be helpful by hosting a copy of the drivers on a more inviting site. However, that is a dangerous thing to be comfortable with. As a Maker Space that regularly teaches microprocessor hacking to beginners, Decatur Makers has decided to host yet another copy of these drivers. You may or may not trust us as a source, but we didn’t feel safe sending our students elsewhere. We have done (and continue to do) everything in our power to verify and maintain the content of this repo.

The driver for this chip has been in the Linux Kernel for a long time. (Introduced in commit 6ce76104 that was released in Linux Kernel v2.6.24 Jan 24 2008) If your Kernel does not support this chip, you are probably very out of date and have severe vulnerabilities to worry about.

Even though Linux users should never need this, we’re going to put the information here.

  Warning: Installation for macOS is [now] very simple. The internet is littered with links to unsigned drivers and out of date instructions telling you how to [recklessly] disable macOS security features that are in place to protect you from these kinds of things. Do not follow them! (If you have done this in the past, undo it.)

  I really suggest you install using homebrew. If you do not have brew installed, you should install it. It is the most common way to install things on a Mac that don’t come from Apple’s App Store.

  1. Open the Terminal (use Spotlight to find it if you must)
  2. If you do not have homebrew, install it.

  /usr/bin/ruby -e "$(curl -fsSL https://github.com/Homebrew/install/raw/master/install)"

      Установка драйверов

      В набор входит “китайская” Ардуино-совместимая плата, у которой для подключения по USB используется контроллер CH340/CH341. Чтобы он распознавался компьютером, нужно установить драйвер.

      Скачать драйвер можно по ссылке:

      Запускаем и в появившемся окошке нажимаем INSTALL. Готово!

      

      Если во время установки Arduino IDE вы по какой-то причине пропустили установку драйверов, то их можно установить вручную из папки с программой, расположенной по пути

      • C/Program Files/Arduino/drivers (для 32-х разрядной системы)
      • C/Program Files (x86)/Arduino/drivers (для 64-х разрядной системы).
      • dpinst-x86.exe (для 32-х разрядной системы)
      • dpinst-amd64.exe (для 64-х разрядной системы)

      

      Драйвер CH341 для Mac можно скачать по ссылке с моего сайта , либо со страницы источника . Если у вас будут какие-то проблемы с OSX Sierra и выше, читайте вот эту статью .

      Рекомендация от подписчика – устанавливать версию драйвера v1.4 вот отсюда

      В Linux уже встроен необходимый драйвер, но Arduino IDE может отказаться с ним работать: Linux определяет ардуинку как устройство ttyUSB*, обычно это ttyUSB0 (это можно узнать командой dmesg в терминале), то есть в системе появляется интерфейс /dev/ttyUSB0. Чтобы с ним работать, нужны права доступа. Читать и писать на устройство /dev/ttyUSB0 имеет пользователь root и пользователи группы dialout. Работы с правами суперпользователя лучше избегать, поэтому следует занести своего пользователя в группу dialout. Это можно сделать следующей командой (обратите внимание, команда whoami в обратных кавычках)

      sudo usermod -a -G dialout `whoami`

      После этого нужно перелогиниться. Дальше запускаем Arduino IDE и в меню «Инструменты/Порт» ставим галочку напротив /dev/ttyUSB0.

      Вся информация по работе с IDE на данной ОСи есть вот в этой статье

      Драйвер FT232

      На Wemos Mini в некоторых партиях (003) стоит преобразователь FT232. Для него нужен отдельный драйвер:

      Скачать, распаковать архив и установить. Wemos отобразится как USB Serial Converter
