The PL2303 is a USB-to-serial bridge controller integrated circuit (IC) produced by Prolific Technology Inc. This chip is commonly used in various electronic devices and applications to enable communication between a computer or other USB host and devices that use serial communication protocols. The PL2303 chip essentially serves as a bridge between the USB interface, which is prevalent on modern computers, and serial ports, which are still found in many electronic devices.

The primary purpose of the PL2303 chip is to provide a means of connecting devices with serial interfaces, such as microcontrollers, GPS receivers, barcode scanners, and other industrial or consumer electronics, to a computer or other host device via a USB port. It converts the USB signals to serial signals and vice versa, allowing for the transmission of data between the USB-equipped host and the device using serial communication. Here’s a short guide on how to install the latest pl2303 driver on Windows 11.
