The RS232 TTL Converter Cable Kit is an efficient solution for converting RS232 signals to TTL levels (3.3 to 5.5V), making communication between electronic devices with different signal standards easier.
This kit includes a double-sided printed circuit board with silkscreen and two mounting holes, assembled and tested to ensure quality and operation.
- Incorporates the genuine MAX3232 chip, recognised for its reliability in signal conversion.
- Works with a 3V to 5.5V VCC power supply, adapting to a range of applications.
- Supports transmission speeds of up to 250 kbit/s, ensuring fast and stable communication.
- Features two drivers and two receivers for efficient bidirectional communication.
- Compatible with RS232 serial ports on computers or USB to serial adapters.
- Requires a DB9 male to female serial cable (straight through) to connect to the computer's RS232 port.
Typical uses:
- Connection and communication with GPS units.
- Interface with XBOX consoles for development or diagnostics.
- Programming and communication with Microchip PIC microcontrollers and Basic Stamps.
- Electronics projects that require signal level adaptation between RS232 and TTL.
Compatibility: This converter is compatible with devices that use RS232 signals and need TTL communication, including electronic equipment, mobile phone systems and other serial devices.
Thanks to its compact design and high quality, the RS232 TTL Converter Cable Kit is an essential tool for technicians, developers and electronics enthusiasts who need a reliable solution for serial signal conversion.

Customer Questions & Answers
What advantages does the MAX3232 chip offer over other RS232-TTL converters available on the market?
The MAX3232 stands out for its wider supply voltage range (3.3 to 5.5 V), low operating current and high reliability in logic level conversion. Unlike variants such as the classic MAX232, the MAX3232 can interface with modern 3.3 V logic systems, broadening compatibility with current microcontrollers and modules.
What are the physical dimensions of the module and what exactly is included in the kit?
The module measures approximately 40 mm x 25 mm and weighs less than 20 g. The kit includes the assembled board with the MAX3232-based converter, the interconnection cable and TTL connection pins. The DB9-M/F cable required to connect to the PC RS232 port is not included.
Is there any installation recommendation to avoid communication errors or damage caused by incorrect connection?
It is recommended to connect the RS232 side to the computer/development port first and ensure the correct pinout on the TTL side. Swapping TX/RX is a common cause of failures. Do not connect the module VCC to sources above 5.5 V to avoid damaging the MAX3232. Always use a straight DB9-M/F cable, not a crossed one.
Does the converter comply with any electrical safety or ESD (electrostatic discharge) protection standard?
The MAX3232 IC has internal ESD protection in accordance with IEC 61000-4-2, withstanding typical direct discharges of up to ±15 kV on RS232 data lines. However, the board does not include additional protection at connector level, so caution is recommended in industrial environments.
What is the RS232 TTL Converter Cable Kit used for?
It is used to convert RS232 serial signals to TTL levels, allowing communication between devices with different signal standards.
Which devices is this converter compatible with?
It is compatible with GPS units, XBOX consoles, Microchip PIC microcontrollers, Basic Stamps and other devices that use RS232 or TTL signals.
What type of cable do I need to connect the converter to a computer?
It requires a DB9 male to female serial cable (straight through) to connect the converter to the computer's RS232 port.
What is the maximum data transmission speed?
The maximum speed is up to 250 kbit/s, ensuring fast and stable communication.
What voltage range does the converter support?
It operates with a power supply between 3V and 5.5V VCC.
