FTDI, Future Technology Devices International Ltd
RS-232, UART USB to Serial
Active

Overview

The USB-RS232-PCBA is a compact USB to RS232 level UART converter module built around the FT232RQ IC. It provides a complete hardware solution for converting USB signals to RS232 serial protocols, featuring integrated electronics and LED indicators on a small PCB form factor.

Why Choose This Part

This module simplifies design by handling the entire USB protocol on-chip, requiring no specific USB firmware development. It includes an internal EEPROM for storing USB VID/PID configurations and features FTDIChip-ID for enhanced hardware security.

Applications

Legacy Equipment Integration
Provides a modern USB interface for industrial machinery and legacy peripherals that originally used DB9 RS232 ports.
Embedded System Debugging
Acts as a bridge for developers to monitor serial logs and send commands from a PC to an embedded target with RS232 levels.
Industrial Automation
Enables PC-based control of PLCs, sensors, and actuators that communicate over RS232 serial links.
