Adafruit Perma-Proto Half-sized Breadboard PCB - 3 Pack!
Best prototyping solution for makers building compact, permanent electronic projects.
This pack of three Adafruit Perma-Proto Half-sized Breadboard PCBs provides a robust alternative to traditional perfboards. Mimicking the familiar layout of a half-sized breadboard, these PCBs simplify component placement with clear white silkscreen markings. The underside features a 5-hole pad design and four power bus lines, all supported by thru-plated holes for enhanced durability and reworkability. A gold finish prevents oxidation, and two mounting holes allow for secure integration into projects, fitting perfectly within an Altoids-sized mint tin for convenient prototyping.

Know before you buy
The layout is identical to a standard half-sized solderless breadboard, featuring 30 rows of double 5-hole pads and four dedicated power rails. This makes it easy to transfer your circuit directly from a temporary breadboard to a permanent, soldered version.
Yes, the board features 1.2mm drill holes, which are large enough to accommodate most standard through-hole components, headers, and wires comfortably.
Yes, the dimensions are specifically designed to fit within an Altoids-sized mint tin, making it an excellent choice for compact, portable, or handheld projects.
The gold plating prevents oxidation, which ensures that your solder joints remain reliable and conductive over a long period. It also makes the pads much easier to solder compared to standard bare copper or tin-plated boards.
Yes, each board includes two 3.2mm mounting holes, allowing you to securely bolt or screw the PCB into a project box or chassis.
