The DE-9 (DB-9) Male Plug to Terminal Block Breakout makes it easy to create custom DE-9 cables or interfaces without soldering a connector. A solid PCB breaks out all nine pins of the DE-9 plug to screw terminal blocks, allowing quick connections with stranded or solid-core wire.
Ideal for non-standard wiring setups or interfacing with legacy serial devices, this breakout comes fully assembled with a clip-on housing for a clean, secure finish.
Key Features
- Screw Terminal Breakout – All 9 pins broken out to terminal blocks for solderless wiring

- Clip-On Housing – Included for a secure, finished appearance
- Fully Assembled – Ready to use out of the box
Ideal For
- Custom serial cable and RS-232 wiring
- Interfacing with legacy devices and industrial equipment
- Prototyping and test jigs
- Quick wiring changes without soldering
Package Contents
- 1× DE-9 Male Plug to Terminal Block Breakout (fully assembled)
- 1× Clip-on housing
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.
- PCB
- A printed circuit board is a rigid board with copper tracks that connect electronic parts without loose wires. For this kit, the PCBs also form the airplane shape, so they are both the circuit base and part of the finished model.
- RS-232
- An older serial communication standard that uses higher signal voltages than modern microcontroller logic pins. If you are connecting this breakout to a microcontroller, you may need an RS-232 interface or level converter rather than wiring it directly.
- Terminal block
- A connector used to join wires together in a neat, removable, or serviceable way. For this product, it helps split one power input into several outputs without soldering.
