MAX232 RS232 to TTL DB9 Female Serial Port Converter Module with LED Indicators

The Envistia MAX232 (SP3232) RS232 to TTL converter module provides a simple and reliable solution for interfacing devices using RS232 serial communication with TTL-level devices, such as microcontrollers.

This module efficiently converts RS232 signals from a computer’s serial COM port (DB9) to TTL logic levels (0-5V or 0-3.3V), enabling seamless communication between your computer and popular microcontrollers like PIC, Atmel, Arduino, and more. Stop struggling with incompatible signal levels – this module makes serial communication a breeze!

Key Features:

• RS232 to TTL Conversion: Effortlessly converts RS232 signals to TTL logic levels, simplifying communication with microcontrollers and embedded systems.
• SP3232 Transceiver IC: Featuring the advanced SP3232 IC, this module offers lower power consumption and wider voltage support (3.3V-5V) compared to traditional MAX232 ICs. This provides greater flexibility and efficiency for your projects.
• DB9 Female Connector: Equipped with a standard DB9 female connector for direct and easy connection to computers and other RS232 devices using a standard serial cable.
• LED Indicators: Includes dedicated Power, RX (Receive), and TX (Transmit) LEDs for clear visual indication of module status and data transfer activity. Troubleshooting and monitoring your serial communication has never been easier!
• Wide Compatibility: Compatible with a vast range of microcontrollers (PIC, Atmel, Arduino, ESP32, etc.) and any system with TTL serial communication capabilities.
• Compact and Convenient: Small form factor for easy integration into your projects.
