What is CH340?

CH340 is a USB to Serial chip. It allows the USB to be converted to serial interface and serial signals to USB. Usually, it’s used in USB programming cables such as the Baofeng programming cable and the development boards such as the Arduino NANO.

Generally, when you plug your device with a CH30 chip included, the device will work immediately, as the driver for the device will be installed automatically through the operating system.

However, Windows is not perfect and the driver sometimes cannot be installed. If the driver is not installed successfully, your device won’t be recognized by Windows. In that case, to make your device work properly, you’ll need to install the driver on your own. Read on to learn how to download and install the CH340 driver on Windows 10.
