About this item

This 2.54 mm pitch, 40‑pin male double‑row header strip—comprising two parallel rows of 20 square-pin posts—offers reliable, stackable connectivity in a compact form factor. Designed for through-hole mounting, its industry-standard 2.54 mm pitch ensures compatibility with breadboards, ribbon cables, and PCBs, making it ideal for electronics prototyping and modular hardware interfaces. The strip’s breakable construction allows you to manually cut it into smaller segments to suit custom pin counts, while built-in standoffs facilitate easier cleaning of solder residues post-assembly. Its stackability enables seamless side-to-side or end-to-end expansion for scalable pin configurations, perfect for versatile modular design. The robust square posts are sturdy enough for repeated insertion of jumper wires or connectors. With dimensions around 50 × 5 × 12 mm (L × W × H) and a lightweight profile (~1 g), it balances durability with flexibility. Backed by a 15‑day sealed‑product warranty, this header strip is a practical and dependable component for both hobbyists and professionals designing custom circuits and electronics systems.
