FT232R - USB 2.0 to UART (RS232) Bridge Interface Evaluation Board
Active164 in stock

Overview

The UM232R is a USB to serial UART evaluation module based on the FT232R interface IC. It is designed as a 24-pin DIP module that plugs directly into a standard 0.6-inch wide socket or breadboard, providing a simple way to add USB connectivity to legacy hardware or prototypes. The board handles all USB signaling and protocols on-chip, requiring no USB-specific firmware programming.

Why Choose This Part

This module features an integrated 1024-bit EEPROM and a clock generator output (6-48MHz), reducing the need for external timing components. It supports a wide range of data rates from 300 Baud to 3MBaud and includes built-in level converters to interface with logic ranging from 5V down to 1.8V.

Applications

Legacy Peripheral Upgrades
Replacing RS232 or RS422/RS485 level shifters to provide modern USB connectivity to existing microcontroller designs.
Rapid Breadboard Prototyping
Quickly adding a serial debug console or data logging interface to breadboard-based MCU projects using the 0.1-inch pitch DIP format.
USB Smart Card Readers
Utilizing the integrated unique FTDIChip-ID and security features for hardware-locked peripheral applications.
FPGA Configuration and Debug
Providing a high-speed asynchronous or synchronous bit-bang interface to communicate with or configure FPGA/CPLD devices.

Getting Started

To begin, plug the module into a 24-pin DIP socket and connect a USB cable; the unit can be bus-powered or self-powered depending on the jumper settings. FTDI provides royalty-free Virtual COM Port (VCP) and D2XX drivers for most major operating systems. Configure the CBUS pins via the MPROG or FT_PROG utility to utilize features like hardware flow control or LED status indicators.
