RS232 to TTL Serial Interface Module

The RS232 to TTL Serial Interface Module is designed with the MAX3232 transceiver integrated circuit (IC), serving as a bridge between TTL and RS232 ports, facilitating seamless serial communication.

Typically, these boards feature a DB9 connector soldered at one end and four header pins for jumper cables at the other. The jumper cables allow users to connect wires to a breadboard or microcontroller project board, while the DB9 connector directly interfaces with a computer’s COM port.

The MAX3232 IC, packaged in a 16-pin narrow SO format, operates within a voltage range of 3.0V to 5.5V and includes two receivers and two transmitters. It supports a maximum guaranteed data rate of 120 kbps and requires four 0.1µF charge-pump support capacitors. This module is compatible with the well-known MAX3232 IC pins and interfaces with systems featuring UART, making it suitable for use with ATMEL and PIC microcontrollers.

The MAX3232 RS232 Serial Port to TTL Converter Module with a DB9 connector operates at 5V and is compatible with female serial TTL and serial modules. It can be employed to expand the serial port of microcontroller modules and upgrade equipment such as DVD players, routers, and hard drives.
