## Summary description

Alcasa JW40-020MM-3 jumper wires are 20 cm solid-tip leads designed for breadboard prototyping.

Ideal for circuit prototyping, testing connections and educational electronics projects.

## Long description

Alcasa JW40-020MM-3 jumper wires are 20 cm solid-tip leads designed for breadboard prototyping. This pack of three multicolour solid (male) tip wires provides reliable, straight connections for solderless breadboards and standard 0.1" header pins. The wires are intended for short interconnections in low-voltage electronic circuits, enabling straightforward assembly and quick reconfiguration of prototype layouts.
Advantages
Solid-tip construction ensures stable insertion into breadboard sockets and header pins with minimal wobble, supporting repeatable connections during testing and modification. The 20 cm length offers a balance between reach and tidy wiring for most prototyping scenarios. Multicolour insulation helps visually separate signal paths and makes tracing connections easier during debugging and assembly.
Suitable for
 Breadboard prototyping and circuit assembly
 Connecting microcontroller pins to sensors and modules
 Educational electronics and lab exercises
 Temporary wiring for testing and troubleshooting
Key specifications
 Conductor type: solid core wire
 Tip type: male (solid) pins for insertion into breadboards and header sockets
 Length: 20 cm per wire
 Pack quantity: 3 wires
 Insulation: multicolour PVC or similar insulating jacket
 Intended voltage: low-voltage electronic circuits (typical prototyping use)
How to use
Insert the solid male tip into the desired breadboard row or header pin until it seats firmly. Route the insulated wire to the target connection point and insert the other end in the same way. Use the different colours to map signals, power, and ground for easier identification. Remove or reposition wires by pulling them straight out to avoid bending the tip. For repeated use, inspect tips for deformation and replace wires that no longer maintain a secure fit.
Usage recommendations
Use these solid-tip jumper wires for temporary prototyping and educational projects in low-voltage environments. Avoid using them in high-vibration conditions or for permanent installations where stranded, crimped, or soldered connections are required. Keep wires away from sharp edges and high-temperature surfaces to preserve insulation integrity.
