This double-row, 80-pin (2×40) straight 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 dual-row length you need.
Standard 0.1" pitch ensures compatibility with breadboards, perfboards, PCB footprints, and female header sockets. The dual-row configuration is ideal for wide bus connections, GPIO headers, and other multi-pin interfaces.
Key Features
- 2×40-Pin (80 pins total) – Breakaway design, snap or cut to any dual-row length
- Straight Orientation – Standard vertical mounting on PCBs and perfboards
- 0.1" (2.54mm) Pitch – Industry-standard spacing for broad compatibility
- Male Header Pins – Mates with standard female headers and breadboards
Ideal For
- Raspberry Pi and other SBC GPIO headers
- Dual-row bus connections and multi-pin interfaces
- Prototyping and PCB projects requiring custom-length dual-row headers
Package Contents
- 1× 2×40-pin straight breakaway male header
Jargon buster
Plain-language definitions for the technical terms used above.
- GPIO
- General-purpose input/output pins are microcontroller pins you can set in software to read signals, switch devices on and off, or connect to peripherals. The number of GPIO pins matters because it limits how many buttons, LEDs, sensors, and other parts you can wire directly to the board.
- 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.
