The latest iteration of boards have taken advantage of an easy-to-use USB-to-Serial adapter based on the CH340C IC from WCH. The chip works with 5V and 3.3V systems and should auto-install on most operating systems without the need for additional drivers. The UNO Scout uses the CH340C IC to quickly and easily convert serial signals to USB. It’s a great lower-cost alternative to the extremely popular FTDI Basic.

The CH340 has been tested on:

  • Windows 7/10

  • Mac OSX

    • v10.10.5 (Yosemite)

    • v10.11.6 (El Capitan)

    • v10.13.0 (High Sierra)

    • v10.14.5 (Mojave)

  • 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:
