The 0.100″ (2.54 mm) 2×4-Pin Straight Female Header is a double-row, 8-pin socket strip designed to mate with standard 0.1″ pitch male headers. Its compact dual-row footprint is commonly used for small bus connections and module interfaces.
A 2×4 configuration is often found on JTAG debug headers, small sensor modules, and compact board-to-board interconnects where eight pins are needed in a space-efficient arrangement.
Key Features
- 0.1″ (2.54 mm) Pitch – Industry-standard spacing compatible with breadboards and perfboard
- Straight Orientation – Mounts perpendicular to the PCB for standard vertical connections
- 2×4-Pin Configuration – Double-row, 8-position socket
- Through-Hole Mounting – Solders directly to standard PCBs
Ideal For
- JTAG and debug header connections
- Sensor module interfaces
- Compact board-to-board links
- Prototyping and custom interconnects
Package Contents
- 1× 0.100″ (2.54 mm) 2×4-Pin Straight Female 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.
- JTAG
- JTAG is a hardware debugging and programming interface used to inspect and control chips at a low level. It matters for advanced development because it can help diagnose firmware problems that are hard to see through normal serial output.
- 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.
