NOTE: This Arduino Clone is based on the CH340 USB chip. Sometimes it is necessary to install the driver for Windows or Mac. This is actually rarely needed on Linux.

First try whether it works without installing the driver. If a COM port is available in the Arduino IDE that you can upload to, then everything is already fine 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
