General Description
Make connections quickly and reliably with this breakout board, which brings every pin of its DB9 connectors out to screw terminals.
These breakout boards feature two DB9 connectors (one male, one female) wired 1:1, with all pins connected to screw terminals for easy wiring connections. Having two connectors allows the board to be easily inserted "in-line" with an existing connection, allowing signals to pass through while being monitored, or to work with "daisy-chained" equipment.
Each pin, including shield, is also brought to solder pads (4 per pin) at 0.1" spacing, allowing easy addition of pin headers or other components. Please note that the breakout boards are manufactured with a connection between each connector pin and the corresponding terminal block position; no soldering of any type is necessary. The solder pads simply provide an area for making optional connections to additional headers or other components.
This breakout board is perfect for production applications as well as experimentation and prototype work. It is helpful for working with RS-232 serial ports, MODBUS connections, I/O cards, and other devices that use a DB-9 connector.
Technically, the correct term for a DB9 connector is DE9, but that term is not commonly used.

A breakout board is sometimes referred to as a "transition module", "terminal board", "terminal block", "breakout box", "breakout adapter", "terminator", or "interface module".
