Some non-Arduino devices with generic USB chips.Ports that do not belong to an Arduino-compatible device, but are detected and shown by Arduino IDE anyway:.Various “clone” board with generic USB chips such as the CH340.The “classic” Arduino Nano, which uses a FTDI USB chip.Arduino-compatible boards that use generic USB chips:.The types of unidentified ports shown by Arduino IDE can be grouped in two categories: This example shows the board selector and Tools > Port menu on Windows when an Arduino UNO board and one other unidentified device is connected: In this case, it will appear as an “Unknown” device in the board selector and show only the port name in the Tools > Port menu. In some cases, the port information is not sufficient to determine the type of board that’s connected, or if the connected device is a compatible board at alL.In the Tools > Port menu, the board name will appear after the port name, enclosed by parentheses. If Arduino IDE is able to identify a device as an Arduino board, it will the board name instead of “Unknown” in the board selector.

If there are “Unknown” devices in the board selector and without a board name in the Tools > Port menuĪrduino IDE will list detected serial ports in the board selector and Tools > Port menu.

If you’re using an Arduino-based “clone” board with a CH340 USB chip, you may need to manually install CH340 drivers.If you’re using a classic Arduino Nano, you may need to manually install FTDI drivers.Alternatively, select your board in the Tools > Board menu. When selecting an “Unknown” port you will be prompted to select the board type manually.
In earlier versions of Arduino IDE 2, the Tools > Port menu option would only be displayed if at least one device was detected on a port.Ensure you’ve connected your board with a working data USB cable.Learn what to do if your board is missing from the board selector or Tools > Port menu.
