This Jumper Wire Kit is a fundamental assortment for electronics prototyping, designed to provide reliable semi-permanent connections on breadboards or between PCB headers. Unlike standard "dupont" wires with plastic housings, these are Double-Head Tin-Plated wires, meaning both ends are pre-stripped and coated with solder for easy insertion and maximum conductivity.

Specifications

• Length: 20cm
• Wire Type: Double-head Soldering Tin (Pre-stripped and tinned)
• Total Quantity: Approx. 100 pieces
• Number of Colours: 5 (Red, Black, Yellow, Blue, Green)
• Quantity per Colour: Approx. 20 pieces per colour
• Core Material: Copper with Tin Plating

Features

• Ready to Solder or Plug: The tin-plated ends prevent the copper strands from fraying, making them easy to plug into breadboard holes or solder directly onto perf-boards and PCBs.
• Color-Coded Organization: With five distinct colours, you can easily organize your circuit (e.g., Red for VCC, Black for GND) to simplify troubleshooting and prevent wiring errors.
• Flexible Length: The 20cm length provides enough reach for connecting components across large breadboards or linking multiple boards together.
• High Conductivity: The tin plating protects the copper core from oxidation, ensuring low-resistance connections over time.
• Durable Insulation: Features standard PVC insulation that is flexible enough for tight routing while protecting against short circuits.

Common Applications

• Breadboard Prototyping: Quickly jumping connections between components like LEDs, resistors, and integrated circuits.
• PCB Rework: Soldering onto existing boards to bridge broken traces or add new test points.
• Arduino & Raspberry Pi: Connecting sensors and modules to microcontroller pins during the development phase.
• Educational Kits: An essential item for student electronics labs and DIY hobbyist projects.

Usage Tips

• Breadboard Fit: These tinned ends are specifically sized to fit snugly into standard 0.1 inch (2.54mm) pitch breadboard holes.
• Permanent Soldering: If you decide to move your project from a breadboard to a permanent PCB, these wires can be soldered directly into through-holes without any further preparation.
• Avoid Over-Bending: While the wires are flexible, repeated sharp bending at the point where the tinning ends and the insulation begins can eventually cause the wire to snap. Use needle-nose pliers for precise, gentle shaping.
