Driver information

This Arduino clone uses the CH340 USB chip. In some cases, it is necessary to install a driver, especially on Windows and Mac. On Linux, this rarely occurs.

First check if the board is automatically recognized in the Arduino IDE. If a COM port appears, driver installation is not necessary.

If installation is needed, you can download the drivers here:

• CH340 driver for Windows
• CH340 driver for Mac
• CH340 driver for Linux

Note: downloading and installing drivers is at your own risk. We cannot guarantee that the drivers are always up-to-date and are not responsible for any malfunctions.
