MAX3232 RS232 to TTL Serial Port Converter Module

MAX3232 RS232 to TTL Serial Port Converter Module

The MAX3232 RS232 to TTL Serial Port Converter Module is a reliable and compact device designed to bridge the communication gap between RS232 devices and TTL logic systems. Based on the MAX3232 IC, this module efficiently converts the voltage levels of RS232 (±12V) to TTL (0-5V or 0-3.3V), enabling seamless communication between microcontrollers and older RS232-compatible hardware like PCs, GPS modules, or industrial equipment.

The module supports full duplex (two-way) communication and operates on both 3.3V and 5V logic, making it compatible with a wide range of devices. It's ideal for interfacing microcontrollers like Arduino, Raspberry Pi, and STM32 with legacy RS232 devices, making it a valuable addition to industrial automation, embedded systems, and prototyping projects.
