This single-row, 4-pin straight female header with 0.1" (2.54mm) pitch is designed to mate with standard 0.1" male headers. It provides a reliable socket connection for board-to-board and board-to-wire applications.
The compact 4-pin length is commonly used for I2C, SPI, and sensor connections. Standard 0.1" pitch ensures compatibility with breadboards, perfboards, and PCB footprints.
Key Features

- Socketing small breakout boards
- Prototyping and breadboard projects
Package Contents
- 1× 1×4-pin straight female header
Note: Order quantity must be a multiple of two.
Jargon buster
Plain-language definitions for the technical terms used above.
- breakout
- A breakout board carries a small or fine-pitched component and brings its connections out to standard, breadboard- and header-friendly pins. Describing a part as a breakout means it can be wired into a project without soldering directly to the component's tiny contacts.
- Headers
- Rows of connector contacts on a fixed pitch (commonly 2.54 mm) used to link a board to a breadboard, jumper wires, or another board. They come as male pin headers and female socket headers; when a module ships with pre-soldered headers it can be used straight away, whereas bare pads require soldering the pins yourself.
- I2C
- I2C is a two-wire communication bus used by many sensors and small modules. It matters because several I2C devices can share the same two wires, but each device needs a compatible address and your controller must support I2C.
- PCB
- A printed circuit board (PCB) is a board, usually rigid, with etched copper tracks that connect electronic components together without loose wiring. Components are mounted on the board and signals route between them through the copper layout.
- SPI
- A fast serial communication bus often used for displays, memory cards, and sensors. It matters because SPI devices need specific pins for clock and data, plus a separate chip-select line for each device.
