You can snap or cut it to the exact length you need, making it a handy “one part fits many jobs” connector for prototyping and custom wiring. Compatibility-wise, the **2.54 mm spacing** matches standard Arduino shield headers, breadboards, perfboard/stripboard and most 0.1\" female sockets. The key difference from typical male headers is the **double-sided long pins**: it can act as a **female-to-male adapter** when plugged into a female header, and both ends are suitable for **wire-wrap**. It’s not the right choice where you specifically need short solder tails (for low-profile builds or guaranteed standoff height), or where the mating connector expects a different pitch. Typical uses include making removable connections between boards, bringing signals through a board so you can connect on both sides, building quick adapter “stacks” with female headers, and wire-wrap prototyping without needing a separate long-tail pin strip. Compared with standard breakaway male headers (short solder side), this one is more versatile for pass-through and wire-wrap, but can sit taller and may be less tidy in tight enclosures. Useful complements: pair it with matching **0.1\" female headers** for plug-in adapters, or use it with prototyping boards for permanent builds. ### Key Features - **Pin Count / Rows:** **1×40** (single row), breakaway to any length - **Pitch:** **0.1\" (2.54 mm)** standard spacing - **Pin Style:** **Double-sided long pins** (extended on both sides) - **Orientation:** **Straight** (vertical) - **Mounting:** **Through-hole** header strip - **Wire-wrap Support:** **Wire wrap compatible** on both ends ### You Might Also Like - [Raspberry Pi 5](https://littlebirdelectronics.com.au/products/raspberry-pi-5) — $102.00 - [Hummingbird Duo micro:bit Adapter](https://littlebirdelectronics.com.au/products/hummingbird-micro-bit-adapter) — $46.00 ## Description This single-row, 40-pin straight male header strip with 0.1" (2.54mm) pitch features extended pins on both sides of the plastic spacer. The breakaway design lets you snap or cut it into any length you need. Unlike standard male headers where one side is short (for soldering), this double-sided version has long pins on both sides. This makes it useful as a female-to-male adapter when inserted into a female socket, and both sides are compatible with wire wrap connections.
