These 1×4-pin crimp connector housings let you quickly build custom cables that mate with standard 0.1" (2.54mm) spaced connectors. Pair them with pre-crimped terminal wires to create reliable, removable four-wire connections in a single inline housing.
Compatible with male and female headers, solderless breadboards, and other 0.1"-pitch connectors, these four-pin housings are a popular choice for sensor leads, servo connections, and I2C/SPI wiring.
Key Features
- 0.1" (2.54mm) Pitch – Industry-standard spacing for broad compatibility
- 1×4-Pin Configuration – Compact housing for four-wire connections
- Versatile Compatibility – Works with male headers, female headers, and solderless breadboards
- Snap-In Design – Pre-crimped terminal wires snap securely into place
Ideal For
- Four-wire cable assemblies (I2C, SPI, sensor connections)
- Prototyping and breadboard projects
- Custom wiring harnesses
Package Contents
- 10× Crimp connector housings (1×4-pin)
Jargon buster
Plain-language definitions for the technical terms used above.
- 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.
- servo
- A servo is a motor with built-in position control, usually told to move to a specific angle by a control signal. It matters when you need repeatable movement, such as steering, arms, flaps, or linkages, rather than continuous spinning.
- 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.
