PL2303 USB to TTL Converter Module

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.
