PL2303 UART Module integrated with PL2303 IC from Prolific Technology, which is a single-chip USB to UART bridge IC. This USB-to-UART bridge controller provides a simple solution to update the design of the RS-232 using minimal components and PCB space. Royalty-free Virtual COM Port (VCP) allows device drivers as a COM port in PC applications. This module allows an asynchronous serial data bus (UART) with a USB 2.0 full-speed function controller, USB transceiver, and full modem control signal.

PL2303 Module Overview
The main USB to UART bridge IC is PL2303.
This PL2303 UART module is a USB to TTL UART Converter module which is based on PL2303 Bridge by Prolific Technology. This PL2303 UART module is compliant with USB2.0 full-speed devices with an integrated transceiver. It has real-time LEDs on the data lines that provide data transfer status in real-time. A 500 mA of a self-recovery fuse is used for protection purposes.
This module can be used as a standard serial port with Laptops that don’t have a standard serial port. This module creates a virtual COM port using USB on your computer which can support various standard Baud Rates (300 bps to 1 Mbps) for serial communication. This module includes the TX (transmit) and RX (receive) data signals.
Interfacing Diagram
