CKANDAY A-3PCS-breadboard+65p-wires-US Solderless Breadboard Kit, 830/400/170 Points

Three solderless breadboards provide 830, 400 and 170 tie points for circuit work at different scales. The panels are made from ABS plastic, with tin-plated phosphor bronze contact sheets. The set also includes 65 flexible jumper wires with copper cores. Choose a larger board for a broader prototype layout or a mini board when a compact circuit is the priority.

Key takeaways

The three board sizes make it easier to match the working surface to a project, whether you are assembling a more involved trial circuit or testing a smaller arrangement. The 830-point board has a 630-point IC circuit area and two 100-point distribution strips, providing four power rails. The 400-point board has a 300-point IC circuit area and two 50-point distribution strips, also providing four power rails. The 170-point mini board offers a compact format for smaller setups.

The boards use a solderless design, so circuit layouts can be assembled, adjusted and reused without soldering. Letters and numbers mark the rows and columns to help with component placement and circuit organization. The included flexible jumper wires are about 20 cm long and come in 10 assorted colours, making connections easier to distinguish as you build and change a layout.

Best use cases

This kit is suited to prototyping circuits, electronic and electrical experiments, Arduino breadboard kit projects and Arduino proto shield work. It can also be used for PCB projects and PC motherboard work. For a project with several components or a wider layout, the 830-point board gives you more working area, the 400-point board offers a mid-sized alternative, while the mini board is handy when a compact arrangement is all you need.

For example, you can lay out a trial circuit on one board, use the numbered and lettered markings to keep track of positions, and connect components with the supplied jumpers. If the project changes, the solderless connections let you rework the arrangement instead of building a new soldered circuit. Multiple breadboards can be spliced together and expanded, so the board setup can adapt to a layout that needs more room.

Usage tips

Start by choosing the board size that gives your circuit a clear layout. Use the row and column markings to plan component positions, and use the distribution strips as power rails when laying out a circuit. The assorted wire colours can help you keep different connections visually distinct. Flexible jumper wires make it easier to connect points across the board while you experiment with the arrangement.

The boards have self-adhesive backing and connection buttons on the side. These features support mounting and joining boards as you organize a prototype. Because the breadboards are reusable, they suit projects where the circuit layout may change during testing or development.

When it makes sense

It makes sense if you want a reusable solderless setup with more than one board size and jumper wires in the same kit. Rather than choosing only a single large breadboard or only a compact one, this set gives you 830-, 400- and 170-point formats for different project layouts. That range is useful for hobby electronics, circuit experiments and Arduino-related prototyping where convenient rearrangement is part of the work.
