NOTE: This Arduino clone is based on the CH340 USB chip. In some cases, it may be necessary to install a driver for Windows or Mac. On Linux, this is rarely required.

First, try whether it works without installing the driver. If a COM port is available in the Arduino IDE that you can upload to, everything is already set up and nothing needs to be installed.

If necessary, you can download the required driver here:

Download CH340 driver for Windows

Download CH340 driver for Mac

Download CH340 driver for Linux
