Serial RS232 to TTL converter module

The Serial RS232 to TTL converter module typically has a DB9 connector for RS232 communication and a set of pins or headers for TTL-level communication. The module contains a built-in MAX3232 IC or similar IC that converts the voltage levels and signal polarity between the two communication standards.

To use the Serial RS232 to TTL converter module, you would typically connect the RS232 interface of the device you want to communicate with to the DB9 connector of the module, and then connect the TTL-level pins of the module to the UART pins of the microcontroller or other device you want to communicate with.
