The RS232 Shield is a standard communication port for industrial equipment.
This module is the base of the MAX232, a dual-drive / receiver with a capacitive voltage generator to provide TIA / EIA-232-F voltage levels from a single 5 V supply. The shield integrates DB9 connectors (disi) which provide connection to various devices with RS232 interface. RS232 headers will make it easy to connect and relay your connections. It provides resource areas to use extra space that is extremely convenient for prototyping.
