Serial Port Mini RS232 to TTL Converter Adaptor Module Board MAX3232 – (Pack of 2)

The Serial Port Mini RS232 to TTL Converter Adaptor Module Board MAX3232 is a compact and efficient bi-directional voltage level translator that allows easy communication between RS232-equipped devices (like PCs and laptops) and TTL-level microcontrollers or embedded systems. Each module in this 2-piece pack is based on the reliable MAX3232 chip, which supports both 3.3V and 5V logic systems.

Designed for seamless data exchange, this converter adapts RS232 voltage levels (typically ±12V) down to safe TTL levels (0–5V or 0–3.3V), and vice versa. It is ideal for a variety of serial communication applications, such as interfacing a microcontroller with a PC, PLC, or RS232 device. This module is a great tool for embedded system developers, electronics hobbyists, and educational labs.
