MAX3232 Mini RS232 to TTL Module
The Serial Port 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.
