MALE DB9 adapter / breakout board with 9 pins connected to screw terminal blocks, allowing simple and quick connections for prototyping or permanent installation. The small footprint means that the end profile of the breakout board is no wider than the connector itself. This can be important for installations where equipment contains multiple connectors which are spaced closely together. These adapter boards can be mounted directly to the equipment without using extension cables. These adapter boards are used for experimentation or prototype work with RS-232 serial ports, I/O cards, and any other device that uses a DB9 connector.
