Prototyping and fabrication products support the design, development, and testing of electronic circuits and systems before full-scale production. This category includes breadboards, perfboards, jumper wires, enclosures, prototyping PCBs, and hardware kits, enabling engineers to build and modify circuits quickly. Widely used in R&D, education, and low-volume development, these tools help verify functionality, simplify debugging, and accelerate the transition from concept to working prototype in electronics design workflows.
