Serial Port Mini RS232 to TTL Converter Adaptor Module Board MAX3232

The Serial Port Mini RS232 to TTL Converter Adaptor Module Board MAX3232 is designed for projects that require a PC or laptop RS232 interface to communicate with 5V TTL logic devices. This module efficiently converts signals between RS232 voltage levels and TTL voltage levels, enabling bidirectional communication between devices. It is suitable for various applications such as PC interfacing, microcontroller projects, robotics, and educational purposes.

  Features:  

1. High-speed operation, using the replaceable MAX232 chip, supporting up to 120kbps.
2. Compatible with PCs or laptops.
3. Supports microcontroller UARTs with 5V TTL signal levels.
4. Single DC supply: wide input range for 3.3V or 5V.
5. Small PCB footprint of 50x40mm.
6. Low current status LED(s) for indication.
7. Very low power consumption.
8. Optional onboard power supply unit (PSU) for internal/external use for quick setup.
9. Power routing to pin 9 on the RS232 connector is possible for specific applications.
