This compact breakout board makes it easy to work with a male DE9 connector, commonly referred to as DB9. It brings the connector out to a maker-friendly plated through-hole header, so you can wire it into prototypes, test fixtures or custom serial-style cable assemblies.
All nine DE9 pins are routed to a 0.1in.-spaced header, with two extra ground connections also available. The board includes two mounting holes for securing it inside an enclosure or to a panel.
Supporting documentation includes the schematic, KiCad files and board dimensions, making it straightforward to integrate into your own hardware designs.

Jargon buster
Plain-language definitions for the technical terms used above.
- breakout
- A breakout is a small circuit board that makes a tiny or hard-to-solder component easier to connect to with standard pins. It matters because this OLED module can be wired into a microcontroller project without needing to solder directly to the display’s fine contacts.
- DE9/DB9
- A 9-pin D-shaped connector commonly used on older computer serial ports, industrial equipment, and test gear. The name matters because this breakout is specifically for wiring those nine connector pins into a breadboard or custom cable.
- PTH
- Plated through-hole means the pin holes are metal-lined so solder connects the pad on both sides of the board. It is useful for connectors and headers that need a strong mechanical and electrical connection.
