RS232 to TTL Serial Port Converter DB9 MAX3232 Module

The RS232 to TTL Serial Port Converter module is designed for easy RS232 (DB9) to TTL logic-level conversion, making it ideal for MCUs, Arduino, Raspberry Pi, and other embedded systems. This module uses the MAX3232 chip, which operates at low power and supports baud rates up to 120kbps.

🔹 Key Features

✔ RS232 to TTL Level Conversion – Enables microcontrollers to communicate with RS232 devices
✔ MAX3232 Chipset – Low-power, high-speed operation
✔ DB9 Male Connector – Standard RS232 interface for direct connection
✔ 3.3V to 5V Operation – Compatible with a wide range of microcontrollers
✔ Supports Baud Rates up to 120kbps
✔ Compact Design – Easy integration into projects

📦 Package Includes

✅ 1 x RS232 to TTL Serial Port Converter Module (DB9, MAX3232 Chip)

🚀 Applications

🔹 Microcontroller Communication (Arduino, Raspberry Pi, STM32, ESP8266, etc.)
🔹 Industrial Equipment Communication
🔹 Embedded System Debugging
🔹 Serial Data Transmission
🔹 RS232 Device Interfacing

📌 How It Works

1. Connect the DB9 Male Connector to an RS232 serial device.
2. Connect the VCC, GND, TX, and RX pins to your microcontroller.
3. Ensure proper voltage levels (3.3V or 5V) for compatibility.
4. Use a serial monitor or microcontroller code to send/receive data.

💡 Note: Ensure proper TX-RX crossover (TX from one device connects to RX of the other).

🌟 Ideal for connecting RS232 devices to modern TTL-based microcontrollers!
