USB to RS232 TTL UART PL2303HX Converter Cable USB to COM Adapter Module

🔌 USB to RS232 TTL UART PL2303HX-Compatible Auto Converter

USB to COM Cable Adapter Module | AuscomTech

A compact, reliable and versatile USB-to-TTL/RS232 adapter ideal for Arduino, ESP32/ESP8266, STM32, routers, PLC configuration and embedded serial debugging. Built around a PL2303HX-compatible chipset, this cable provides stable, high-speed communication between your PC and TTL-level devices.

⚠️ Important Driver Notice (Must Read)

Windows may automatically install an incompatible Prolific driver, which can incorrectly report messages such as:
❌ “Product discontinued”
❌ “PL2303HXA phased out”
❌ “This device cannot start (Code 10)”

This is a Windows driver compatibility issue, not a fault with the cable.

👉 To use this adapter, install the PL2303HX-compatible driver provided.
👉 Do not rely on the Windows auto-installed driver.
