Quick Overview
The DIYables 2.54mm 40-Pin Single Row Male Header Connector is a versatile prototyping component designed for breadboard circuits, PCB assembly, Arduino projects, and DIY electronics. Featuring the industry-standard 2.54mm (0.1 inch) pin spacing, these straight male headers provide reliable electrical connections and mechanical stability for a wide range of electronic prototyping applications.
Each header strip includes 40 straight male pins in a single row configuration with a durable black plastic insulating base and solid metal pins. The headers can be easily cut or snapped to any required length, making them perfect for custom projects that need specific pin counts. Whether you need 2 pins, 8 pins, 20 pins, or any other configuration, simply break the strip at the desired position for a clean, professional result.
This 50-pack value set is ideal for bulk prototyping, repairs, educational workshops, electronics labs, and maker spaces. The straight vertical pin design ensures secure insertion into breadboards, female headers, and PCB through-holes with excellent contact stability. Compatible with Arduino boards, ESP32, ESP8266, Raspberry Pi, prototype boards, and all standard 2.54mm pitch electronics. Perfect for building shields, breakout boards, custom modules, sensor connections, and general-purpose prototyping.
