The is a popular, low-cost RS232 to TTL converter module based on the MAX3232 transceiver IC . It is primarily used to bridge the communication gap between devices that use RS232 serial standards (like older PCs, industrial equipment, or GPS modules) and microcontrollers that use TTL logic levels (like Arduino , ESP32 , and Raspberry Pi ).
