Uninstall any old CH340 drivers via Windows Control Panel, download the latest version from WCH, and ensure your Windows Update is fully updated to recognize the official digital signature. Share public link

The required software is the . This driver makes the USB device appear to your computer as an additional standard COM port (e.g., COM3 on Windows, /dev/cu.usbserial-XXXX on macOS or /dev/ttyUSB0 on Linux). Once installed, any serial terminal program (like PuTTY, CoolTerm, or the Arduino IDE's Serial Monitor) can communicate with the adapter as if it were a built-in serial port.
