Overview

About 140pcs U-Shape Solderless Breadboard Jumper Wire Kit.

The 140-piece U-Shape solderless breadboard jumper wire kit is a set of pre-formed, solid-core wires bent into flat U-shapes so they lie neatly against the surface of a breadboard. Instead of a tangle of flexible leads, you get a clean, organised layout that makes circuits easier to read, photograph and debug. It is one of the most popular accessories among Indian students, hobbyists and lab instructors working with breadboards.

The kit contains 140 wires cut and bent to 14 different lengths, each colour-coded so you can quickly pick the right span between two points. Because the wire is solid 22 AWG copper with tinned tips, the ends push firmly into standard 2.54mm (0.1 inch) breadboard tie-points and hold without wobbling.

At around Rs 130 it is inexpensive, reusable and a genuine time-saver for anyone building prototypes on a solderless breadboard. It pairs perfectly with an MB102 breadboard and flexible Dupont wires for the connections that a flat U-wire cannot reach.

Buying guide

How to choose.

Buy this kit if you build circuits on solderless breadboards and want a clean, professional layout that is easy to trace. It is ideal for students, educators and hobbyists who dislike the mess of flexible leads and want short, direct jumps between nearby holes.

Choose U-shape wires for horizontal runs and short hops; keep a set of flexible Dupont wires on hand for connecting to modules, potentiometers and off-board components that fixed wires cannot reach. Match the kit to a full-size 830-point MB102 breadboard for the most working room.

Pair it with a breadboard, an MB102 power supply module and a Dupont jumper set to have a complete, self-contained prototyping bench.

FAQ

Common questions.

Will these fit any standard breadboard?

Yes. They are made for the universal 2.54mm (0.1 inch) tie-point spacing used by virtually all solderless breadboards and perfboards, including the common 400-point and 830-point MB102 boards.

What is the difference between these and Dupont wires?

These are solid-core, pre-bent into flat U-shapes for tidy, low-profile on-board routing. Dupont wires are flexible, stranded leads with pin/socket ends, better for reaching modules and components off the board. Most builders use both together.

Can I re-bend or cut them to a custom length?

The solid copper wire can be gently re-shaped, but it is not designed to be cut and re-stripped repeatedly. The 14 preset lengths already cover most breadboard spans, so re-cutting is rarely needed.

How many of each length are included?

The 140 wires are distributed across 14 lengths, roughly 10 pieces per length, with the exact colour tied to the length so they are easy to identify.

Are these available in India?

Yes, this is a very common item stocked by BotBit and most Indian electronics suppliers, and it ships across India.
