Most of the MCUs use TTL levels, and the computer serial port generally uses 232 levels. If we want the computer to communicate with the MCU, we need this RS-232 To TTL Converter (MAX3232IDR).
This module is based on Max3232, it supports multiple baud rate communication and theoretically supports communication up to 230400bps baud.
