RS232 to TTL adapter MAX232, provides RS232 port for MCU or Arduino

Description

RS232 to TTL (serial RX/TX) I/O adapter compatible MAX232

This adapter provides a REAL RS232 serial port to micro controllers like Arduino, Raspberry, STM, Pic etc.

It connects on one side to TTL logic level RX/TX lines on a micro controller, and on the other side to RS232 devices like programmers, motor controllers, PLC etc.

The chip includes a step-up DC-DC converter to provide the necessary signal level for RS232 communication.
