    • v10.10.5 (Yosemite)
    • v10.11.6 (El Capitan)

  • Linux
    • Raspbian Stretch (11-13-2018 release) for the Raspberry Pi
    • Raspbian Buster (2019-07-10 release) for the Raspberry Pi
    • Ubuntu v18.04.2, 64-bit

These operating systems have the CDC drivers pre-installed, which means you shouldn't need to install any extra software. However, there are a wide range of operating systems out there, so if you run into driver problems, you can get the archived drivers linked below:

The CH340 is made by WCH. You can find the latest version of their drivers in their English translated website.

Note: At the time of writing, you were only able to find the latest version of their drivers from their website in Mandarin. If you use a Chrome web browser, you had the option to have the web page translated. However, you now have the option of browsing the WCH website in either language.

Updating Drivers

If you have the older CH340 drivers installed, you may need to update them. In the following sections, are the instructions for doing so on each of the tested operating systems.
