UART232-TFC RS232 to TTL Serial Module with RTS/CTS Hardware Flow Control

概述 — UART232-TFC RS232 to TTL Serial Module with RTS/CTS Hardware Flow Control

The Tittron UART232-TFC RS232 to TTL serial module is designed as a compact and reliable development tool for bidirectional level conversion between RS232 and UART TTL signals. Supporting full-duplex communication and RTS/CTS hardware flow control, it helps maintain stable data transmission and reduce packet loss during high-speed serial debugging. It supports a wide 3V--5.5V input voltage, with TTL levels automatically matching the supply voltage for direct compatibility with 3.3V and 5V MCUs, and features standard 2.54mm pin headers for easy wiring on breadboards and development platforms. Ideal for embedded development, serial debugging, and hardware verification, this module allows engineers to quickly validate RS232 and TTL communications through simple loopback tests. It requires an external power supply for operation and supports stable baud rates up to 235Kbps. With clear wiring guidance and built-in ESD protection, it improves signal stability and anti-interference performance, making it an essential debugging tool for developers working with MCUs, Raspberry Pi, industrial controllers, and serial communication testing.
