The RS232 to TTL 5V Signal Converter Module is a professional module for projects requiring PC/Laptop RS232 interface to 5V TTL logic. This module converts signals between RS232 voltage levels and TTL voltage levels. It is bi-directional, where TTL signals are converted to RS232 levels and RS232 levels are converted to TTL levels. It is ideal for use in pc interfacing, microcontroller based projects, robotics, or for experimental and educational purposes.
