(-52%)MAX3232 Serial Module RS232 to TTL Converter is a communication interface board that converts RS232 voltage levels to TTL logic levels, enabling reliable serial communication between microcontrollers and RS232-compatible devices such as PCs, modems, or GPS modules. It features onboard transceiver indicators for easy status monitoring and operates on both 3.3V and 5V logic systems.
Product details
The MAX3232 Serial Module is a bidirectional level converter designed to bridge the voltage gap between RS232 signals (±12V range) and TTL-level signals (0–3.3V or 0–5V). Built around the MAX3232 IC, this module supports serial communication at standard baud rates while maintaining signal integrity and protecting connected devices from voltage mismatches.
It includes onboard charge pump capacitors that generate the required RS232 voltage levels internally, eliminating the need for dual power supplies. The module can be powered from 3.3V or 5V sources, making it compatible with a wide range of microcontrollers such as Arduino, ESP32, STM32, and Raspberry Pi.
Integrated transceiver indicator LEDs (TX/RX) provide visual feedback for data transmission and reception, simplifying debugging and development. The compact PCB design with DB9 connector or pin header interface ensures easy integration in embedded, industrial, or communication applications.
