0.1″ (2.54 mm) Arduino Male Pin Headers (Straight Red 10PCS)

DFRobot 40 Pin 2.54mm Single Row Red Pin Header Strip offers a practical interconnection solution for electronics prototyping, circuit assembly, and embedded hardware development. Built around the widely adopted 2.54 mm (0.1") pitch standard, the connector rail integrates seamlessly with Arduino development boards, solderless breadboards, perfboards, and female header sockets used in robotics controllers. The red-colored header format improves wiring clarity while maintaining reliable electrical contact and mechanical stability. Each 40‑pin strip can be snapped into smaller segments, allowing flexible connector layouts for sensor modules, expansion boards, and rapid hardware experimentation.

Standard 2.54 mm Prototyping Interface

The single‑row connector strip follows the universal 2.54 mm (0.1") pitch widely used across maker platforms and embedded electronics ecosystems. Standardized spacing ensures consistent compatibility with breadboards, prototyping PCBs, and controller boards frequently used in robotics and hardware experimentation. Such universal mechanical alignment allows quick integration into experimental circuits while maintaining dependable electrical connectivity for signal routing, voltage distribution, and modular hardware expansion.

Color-Coded Circuit Organization

A red-colored header rail improves visual organization during circuit assembly and debugging. Color‑coded connectors help separate voltage rails from signal wiring in complex prototyping environments, making hardware layouts easier to understand at a glance. Many electronics developers adopt simple color conventions—such as green for digital I/O, blue for analog inputs, and red for power rails—to reduce wiring confusion and simplify troubleshooting during iterative hardware development.

Flexible Breakaway Design

The 40‑pin header strip features a breakaway construction that allows clean segmentation into shorter connector sections without specialized tools. Such modular adaptability supports custom board layouts, sensor interface boards, and controller expansion modules. Breakaway headers provide convenient configuration for shields, development platforms, and robotics subsystems where different pin counts are required, enabling efficient hardware customization during rapid prototyping and small‑batch electronics assembly.

Colored pin header connectors are commonly used in electronics prototyping environments, robotics controller wiring, and maker hardware projects. Typical applications include signal breakout connections, breadboard circuit construction, custom PCB header installation, and organized power rail distribution. In educational laboratories and STEM Education hardware workshops, clearly identifiable connectors help simplify circuit building while improving reliability and maintainability in embedded system development.
