Unique-Bargains 40Pcs Female to Male Jumper Wire 40cm Rainbow Color

SKU CH-RKKB-933K1

Forty female-to-male jumper wires in rainbow colours, each 40 cm long, separate easily for breadboard and prototype connections

  • 40 pieces cover many breadboard connections at once
  • 40 cm length reaches across standard protoboards easily
  • Rainbow colours let you trace signals instantly
  • Female-to-male ends plug straight into headers and sockets
  • Flat ribbon separates cleanly for tidy terminations

40-piece rainbow jumper wire kit

This set supplies 40 female-to-male jumper wires, each 40 cm long, in a rainbow colour mix. The ribbon-style cable separates easily for clean connections to standard headers, jacks and pins. Net weight is 60 g. It is intended for breadboard prototyping, circuit repair and quick interconnects.

Makers, students and repair technicians needing

Builders who require soldered joints, shielded cables or high-current power distribution should look elsewhere. The 1-pin female-to-male design is not suited for multi-pin connectors or permanent installations.

40 cm length per wire

Every wire measures 40 cm (15.7 inches), which determines reach between components on a breadboard or inside a chassis. Choose a different length if your layout demands shorter or longer jumpers.

Questions about this item

Do these 40 cm jumper wires get warm or draw noticeable power when left connected all day?

They are passive ribbon cables with no active components, so they do not generate heat or consume power beyond the tiny current of the circuit you are building.

What must I already have to use these 40 female-to-male jumper wires?

You need a breadboard, header pins, or compatible connectors with matching 1-pin female and male sockets to plug each end into.

Will these rainbow jumper wires work with older 5 V Arduino boards and legacy sensor modules I still own?

Yes, the plain conductors carry whatever voltage and signal your legacy hardware provides, so they connect to 5 V Arduino boards and older modules without any conversion.
