, ESP8266 modules, and various sensor boards—require an external interface to communicate via serial protocols (UART).
To use the HW-597, you must install the driver. Without it, your computer will likely label the module as an "Unknown Device" or "USB 2.0 Serial".
Windows updates sometimes replace or block unsigned drivers. Uninstall the current driver, download the latest CH341SER from WCH, reinstall, and restart.
This is almost always caused by a bad or loose USB cable, a dusty USB port, or insufficient current supply from a USB hub. Plug the HW-597 directly into your computer's motherboard ports.
With the driver installed, you can now use your HW-597. Let's look at the common use cases.
