Single-Sided Phenolic Prototyping Board

Perfboard for DIY Electronics and Circuit Prototyping

This single-sided phenolic prototyping board is a compact, easy-to-use solution for building permanent through-hole circuits. Commonly described as a phenolic perfboard, protoboard, prototype PCB board, or universal PCB board, it gives you a practical way to solder components into a stable layout for testing, repair, or final assembly. It is a good fit for hobby electronics, classroom use, bench work, and small custom circuit builds where a solderable breadboard is more useful than a temporary plug-in board.

Universal Prototype PCB Board with Standard 0.100 Inch Spacing

Designed for common through-hole components, this universal prototype board features 432 holes on a standard 0.100 inch pitch. That spacing works with many widely used parts, including resistors, LEDs, diodes, DIP ICs, connectors, transistors, sensors, and similar electronic components. The approximate hole diameter is 0.039 inch, which supports many standard component leads used in DIY electronics, repair work, and general circuit prototyping.

Single-Sided Phenolic Protoboard for Easy Soldering

Made from 94HB phenolic material, this single-sided PCB prototype board is thick, rigid, and easy to solder. The flat board surface and centered hole pattern help keep components aligned during assembly, making it easier to create neat, organized layouts. If you need a single-sided phenolic perfboard for soldering and welding electronic components by hand, this board offers a simple and dependable platform for repeated use in electronic experiments and everyday project work.

Compact Perfboard for Repairs, Experiments, and Custom Builds

With an overall size of approximately 1.97 x 2.76 inches, this compact prototyping board is useful when you need enough room for small circuits without taking up too much bench space. It works well for prototype modules, sensor interfaces, LED circuits, connector breakouts, controller support boards, and general-purpose DIY soldering applications. This phenolic protoboard is a practical choice for anyone looking for a solderable prototype circuit board that is simple, versatile, and easy to integrate into one-off builds or low-volume projects.
