Renkforce Jumper Cable JKMF403 — 40-wire bridge set for PCB and breadboard connections

Renkforce Jumper Cable JKMF403 is a set of 40 single-conductor wires for making connections on printed circuit boards and breadboards. The kit includes colorful jumper leads in varying lengths suitable for prototyping, testing and wiring modules, providing a straightforward solution for temporary or semi-permanent signal and power routing during development and repair work.

Advantages

The jumper set offers a large number of individual wires in different colors to simplify identification and routing. Cables are suitable for direct header-to-header or header-to-board connections on Arduino, Raspberry Pi, Banana Pi and similar development platforms. The kit reduces assembly time and helps keep wiring tidy and reliable in test setups and small projects.

Suitable for

• Prototyping on breadboards
• Connecting modules and sensors to Arduino, Raspberry Pi, Banana Pi
• Temporary wiring during testing and debugging
• Small repairs and wiring tasks on PCBs

Key specifications

How to use

Select the required jumper wires by color and length, then insert one end into the source pin or header and the other end into the target pin, header or breadboard hole. For secure connections on development boards such as Arduino, Raspberry Pi or Banana Pi, ensure pins are aligned and fully seated. Use multiple jumpers to route signals, power and ground as needed while avoiding crossing or excessive tension on the wires.

Usage recommendations

For reliable results, use jumpers of different colors to identify signal, power and ground lines. Inspect connections for firm seating before powering your circuit and avoid bending wires sharply near the contact points to prolong cable life.
