Solderless Breadboards

1. Overview

Solderless breadboards are reusable electronic prototyping tools that enable rapid circuit assembly without requiring soldering. They utilize spring-loaded contacts to temporarily connect components, offering a cost-effective platform for testing and development. These boards are essential in modern electronics engineering, education, and DIY projects due to their flexibility, reusability, and ease of use.
