General Description
Make connections quickly and reliably with this breakout board, which brings every pin of its DB9 connector out to screw terminals. This product is available with both male and female connectors.
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.
Need something different? We stock a variety of DB9 breakout board styles and form factors. Please have a look!
A breakout board is sometimes referred to as a "transition module", "terminal board", "terminal block", "breakout box", "breakout adapter", "terminator", or "interface module".

Connector Style
These breakout boards are available with either a Right Angle connector or a Straight ("Vertical") connector. The terms Right Angle and Straight refer to the connector itself, NOT the relationship of the mating cable to the plane of the PCB. In fact, the cable mating to a Right Angle connector is parallel to the PCB, while the cable mating to a Straight connector is perpendicular to the PCB. These are pictured below:

These products are available in two different mounting variants. Product numbers ending with -DIN come with DIN clips already installed and ready to snap onto 35mm or 32mm DIN rail. Product numbers ending with -FT have stick-on rubber feet installed on the bottom side, allowing for benchtop use or panel mounting. For panel mounting, we suggest 1/4" nylon standoffs under the mounting holes, and #6 screws.
