RS232 to TTL Serial Interface Module – MAX3232 Chip – DB9 Connector

The RS232 to TTL serial interface module based on the MAX3232 IC enables reliable communication between RS232 devices and TTL-level microcontrollers. It converts voltage levels bidirectionally, making it ideal for interfacing legacy serial ports with modern embedded systems.

Supporting an operating voltage range of 3.3V to 5.5V, this module is compatible with a wide range of microcontrollers including STM32, NXP, Renesas, and other embedded platforms. It features a DB9 connector for RS232 connection and a 4-pin header for TTL interface, allowing easy integration into development and debugging setups.

With communication speeds up to 250 kbps and a compact PCB design, this module is suitable for programming, debugging, data communication, and upgrading firmware in routers, GPS modules, and industrial systems.
