Product Description

The 2.54mm Male Header Strip is designed for extreme versatility. Each 40-pin strip can be easily snapped or cut into smaller segments (such as 2-pin, 4-pin, or 8-pin) to fit the specific requirements of your project. The straight, square-post design ensures a secure fit when soldered into a PCB or plugged into a female header. The adjustable plastic spacer allows for fine-tuning the mounting height or clearance before permanent soldering.

Key Features

  • Breakable Design: High-quality thermoplastic allows you to snap the strip by hand or with pliers without damaging adjacent pins.

  • Breadboard Compatible: Standard spacing allows for immediate use in rapid prototyping on solderless breadboards.

  • High Conductivity: Brass pins with tin or gold plating provide low contact resistance and excellent solderability.

  • Universal Interface: The standard for connecting Arduino shields, motor drivers, and UART/I2C modules.

  • Single Unit: Ideal for small-scale prototypes or when you only need a specific number of pins for a one-off build.

Technical Details

  • Total Length: Approx. 102mm per strip.

  • Insulation Resistance: 1000 MΩ min.

  • Finish: Tin-plated pins for corrosion resistance.

Prototyping and Engineering Tips from Robogears

  • Soldering Alignment: When soldering headers to a module (like a Nano or an I2C LCD), insert the header pins into a solderless breadboard first, then place the module on top. This keeps the pins perfectly vertical and aligned while you solder.

  • Clean Cuts: While these are "break-away" headers, using a pair of flush cutters results in a cleaner edge compared to snapping them by hand.

  • Avoid Overheating: Use a soldering iron temperature around 320°C–350°C. Heating the pins for more than 2-3 seconds can cause the plastic spacer to melt or warp, causing the pins to become crooked.

  • The "Short" Advantage: These 11.5mm pins are shorter than standard 14mm–18mm versions. Use these when you want a module to sit flush or closer to your main PCB to reduce the overall height of your project.

Package Includes

  • 1 x 2.54mm 1x40 Pin Male Single Row Straight Short Header Strip

Disclaimer

Ensure the headers are not under mechanical stress while soldering. Excessive force on the pins after soldering can crack PCB traces or cold solder joints.
