Pin Headers - 3 Rows, Straight (40 Pins, 2.54 spacing)
by RMRC

Maximize the signal density of your custom electronics projects with the RMRC 3-Row Straight Pin Headers. Engineered with the industry-standard 2.54mm (0.1 inch) pitch spacing, this 3x40 breakaway strip delivers 120 total pin positions in a highly organized, triple-row configuration. The straight vertical layout is perfect for building high-density signal distribution blocks, allowing you to align Ground, Power, and Signal rails perfectly adjacent to one another for direct plug-and-play operations with standard three-wire servo connectors.

This robust triple-row header strip serves a vital purpose across multiple technology, hobby, and defense-testing sectors. In the RC hobby and FPV market, it is a foundational component for pinning out classic flight controllers (such as the Naze32, Dodo, and modern custom platforms) and multi-channel PWM receivers, facilitating neat, stacked wiring runs from a central bus. For the educational and STEM robotics market, these strips provide a tangible way for students to map multi-rail power distribution lines, interface sensor arrays on prototype shields, and learn proper through-hole soldering alignment. For sUAS contractors, enterprise drone integrators, and government testbed operations, this standardized triple-row matrix functions as a highly repeatable, low-cost solution for managing complex telemetry breakouts, bundling multichannel payload logic lines, and terminating diagnostic inputs on surrogate flight development systems.

Tech Tip: While single-row headers snap easily by hand, triple-row carrier strips have additional structural mass. For the cleanest results without fracturing the plastic housing, use sharp diagonal wire cutters or shears to split the header array into your desired custom pin count.

Key Features:

• Triple-Row High-Density Layout: Vertically aligns three parallel rows of 40 pins, perfect for matching standard Ground-Power-Signal servo connector layouts.

• Easy-to-Trim Breakaway Carrier: The rigid plastic housing can be clipped down into smaller multi-pin grids (such as 3x2, 3x3, or 3x6 arrays) to fit custom board spaces.

• Standard 2.54mm Spacing: Built with a universal 0.1-inch pitch, ensuring drop-in compatibility with standard flight managers, receiver grids, and prototyping breadboards.

• Excellent Solder Retention: Through-hole pin legs feature clean plating optimized for effortless capillary solder flow, ensuring rock-solid joints that resist intense field vibrations.

• Rigid Structural Alignment: Holds long rows of pins precisely parallel, preventing pin alignment distortion or internal contact binding during field insertions.

Recommended Items & Needed to Complete (Available at ReadyMadeRC):

To seamlessly integrate this triple-row block into your upcoming hardware build, consider these companion workspace supplies from ReadyMadeRC:

• Connection Routing: Pair with a Clean Male to Male Servo Cable Set (10cm) to cleanly route signals away from the vertical pins with zero wire slack.

• Low-Profile Alternates: Pick up the Pin Headers - 1 Row, Right Angle (40 Pins) variant if your layout demands a horizontal, low-clearance wire configuration.

• Workbench Electronics Essentials: Keep a supply of PE Black Heat Shrink on hand to insulate custom solder terminations or bundle incoming power feeds.

• Precision Soldering Gear: High-grade solder and fine-tip irons to ensure precise, bridge-free connections across the dense triple-row grid.
