This triple-row, 120-pin (3×40) right-angle male header strip with 0.1" (2.54mm) pitch is a versatile connector for electronics projects. The breakaway design lets you snap or cut it into any triple-row length you need, and the right-angle orientation is ideal for low-profile connections where vertical clearance is limited.
Standard 0.1" pitch ensures compatibility with solderless breadboards, perfboards, PCB footprints, and female header sockets. Triple-row strips can be broken into smaller sections, though using diagonal cutters is recommended for a cleaner cut.
Key Features
- 3×40-Pin (120 pins total) – Breakaway design, snap or cut to any triple-row length
- Right-Angle Orientation – Low-profile connections parallel to the board surface
- 0.1" (2.54mm) Pitch – Industry-standard spacing for broad compatibility
- Male Header Pins – Mates with standard female headers and breadboards
Ideal For
- High-density board-to-board connections
- Prototyping and PCB projects requiring triple-row headers
- Low-profile multi-row connector applications
Package Contents
- 1× 3×40-pin right-angle breakaway male header
Jargon buster
Plain-language definitions for the technical terms used above.
- Headers
- Rows of metal pins used to plug a module into a breadboard or connect it with jumper wires. Pre-soldered headers make the module easier to use straight away without needing to solder the pins yourself.
- 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.
