It\u2019s a handy choice when you need more contacts in a small area than a single- or dual-row header can provide, while still staying within the common 2.54 mm prototyping ecosystem. Compatibility-wise, it mates with **2.54 mm pitch male headers/pins** (including standard breakaway male headers and many module pin strips). It\u2019s designed for **through-hole PCBs/perfboard** and mounts **straight (vertical)**. It won\u2019t suit **2.0 mm pitch** systems, **JST**-style wire-to-board connectors, or boards laid out for **single-row or 2\u00d7N headers** unless the matching 3\u00d74 footprint is present. Practical uses include **custom button/LED matrices**, compact interconnects between stacked PCBs, specialised sensor/module breakouts, and space-constrained prototypes where a longer 2\u00d76 header would clash with other components. Compared with **single-row female headers**, this offers higher density in a smaller edge length; compared with **IDC box headers**, it\u2019s simpler and lower-profile but doesn\u2019t provide keyed, ribbon-cable-friendly alignment. Suggested complements: use with matching male pins (e.g. a breakaway header) and prototyping substrates like [Perfboard](https://littlebirdelectronics.com.au/products/perfboard) or [Breadboard](https://littlebirdelectronics.com.au/products/breadboard) (choose based on your project), plus solid-core hookup wire for jumpers. ### Key Features - **Pitch:** **0.1\u2033 (2.54 mm)** - **Positions:** **12-pin (3\u00d74)** - **Rows:** **Triple-row** - **Orientation:** **Straight (vertical)** - **Mounting Style:** **Through-hole** - **Mates With:** **Standard 2.54 mm male headers/pins** - **Included:** **1\u00d7 3\u00d74 female header** ### 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 The 0.100″ (2.54 mm) 3×4-Pin Straight Female Header is a triple-row, 12-pin socket strip designed to mate with standard 0.1″ pitch male headers. Its unusual three-row configuration provides a compact, high-density connection in a small footprint. A 3×4 arrangement is useful for custom matrix interfaces, specialised module connections, and applications where a standard dual-row header would be too long for the available board space. Key Features 0.1″ (2.54 mm) Pitch – Industry-standard spacing compatible with perfboard and PCBs Straight Orientation – Mounts perpendicular to the PCB for standard vertical connections 3×4-Pin Configuration – Triple-row, 12-position socket for high-density connections Through-Hole Mounting – Solders directly to standard PCBs Ideal For Custom matrix and grid interfaces High-density module connections Space-constrained PCB layouts Prototyping and specialised interconnects Package Contents 1× 0.100″ (2.54 mm) 3×4-Pin Straight Female Header **Product Type:** physical ## Images - [Image 1](https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkCjaJJIghwdXIGOwBUSSIMYmxvYl9pZAY7AEY=--d483300521a9d63ce3d59ef771c35ac7979dd62e/image_94a72132-c246-48ce-b29a-9240e15e151c.jpg) - [Image 2](https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkCjqJJIghwdXIGOwBUSSIMYmxvYl9pZAY7AEY=--d668c9b95baa8581ed2c826782e0c7f9d8535f1b/image_da2c9a7e-ae0d-46ad-afed-9608157dc790.jpg) - [Image 3](https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkCj6JJIghwdXIGOwBUSSIMYmxvYl9pZAY7AEY=--7556e1cdb7f775759d7b2148dcfee5e4ed183bee/image_f97d28d6-702d-4b27-8728-bbe3a668e1cf.jpg) - [Image 4](https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkCkKJJIghwdXIGOwBUSSIMYmxvYl9pZAY7AEY=--573a1a1e871bb88661ef6fa99bf8ec7fc4374936/image_5d7d4d5a-33e7-4566-b752-3f4cac1ac5f9.jpg) - [Image 5](https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkCkaJJIghwdXIGOwBUSSIMYmxvYl9pZAY7AEY=--bd21f47e6d3cc0f3593fe4a7a5a39784a2f491d4/image_90cdf680-5ea9-442c-a705-9c5d0475df33.jpg) - [Image 6](https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkCkqJJIghwdXIGOwBUSSIMYmxvYl9pZAY7AEY=--1c2f252c25968f3048996027185f27831b9947c9/image_6e5105ca-c614-4bd4-a117-9d24cb230ba3.jpg) --- ## Finding & Searching Products If a part listed here isn't quite what you need, you can search Little Bird Electronics' full catalogue: - **Search by keyword:** `GET https://littlebirdelectronics.com.au/products.md?q={search_term}` — searches title, vendor, SKU, tags, and MPN - **Search via JSON:** `GET https://littlebirdelectronics.com.au/products.json?q={search_term}` — structured JSON results - **Browse by collection:** `GET https://littlebirdelectronics.com.au/collections/{handle}.json` — products in a specific collection - **Filter in-stock only:** `GET https://littlebirdelectronics.com.au/products.md?q={term}&in_stock=1` - **Individual product detail:** `GET https://littlebirdelectronics.com.au/products/{handle}.md` — full specs, pricing, stock levels, variants Search supports multi-word queries (AND logic).
