These 2 mm pitch 25-pin female socket headers are perfect for connecting to modules and boards that use 2 mm pin spacing instead of the standard 2.54 mm (0.1″) pitch. Each pack includes five 25-pin strips that can be cut to your desired length with diagonal cutters.

Gold-plated contacts ensure reliable connections and long-term resistance to oxidation. The strips can also be stacked side by side for multi-row applications.

Key Features

  • 2 mm Pitch – For modules with 2 mm pin spacing (e.g., XBee, certain sensors)
  • 25 Pins Per Strip – Cut to any length with diagonal cutters
  • Gold-Plated Contacts – Reliable connection with oxidation resistance
  • Stackable – Place side by side for multi-row configurations
  • Pack of 5 – Plenty of headers for multiple projects

Ideal For

  • XBee and other 2 mm pitch modules
  • Custom breakout boards and adapters
  • Prototyping with non-standard pitch components

Package Contents

  • 5× 2 mm pitch 25-pin female socket headers

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.
