Each board has 15 rows of 5-hole connected pads divided into two blocks (just like a standard breadboard), plus four bus lines for two independent power supplies.\n\nThe five-pin rows in each block are electrically connected, so you can mount a 14-pin DIP IC and easily connect other components to its pins without extra wires. All connections are visible from the back side for easy verification.\n\nKey Features (Each Board)\n\n\n15-Row Breadboard Layout – Two blocks of 5-hole connected pads, just like a mini breadboard\n\n4 Bus Lines – Supports two independent power supplies\n\nThrough-Plated, Gold-Finished – Durable pads that resist oxidation and survive rework\n\n1.2mm (47 mil) Drill Holes – Fits components with thicker leads like diodes\n\nNo Solder Mask – Easily cut traces on the bottom side\n\n2 Mounting Holes – 0.125″ holes for #4 or M3 screws, spaced 1.4″ apart\n\n\nSpecifications\n\n\nBoard Dimensions – 1.7″ × 2.0″ (43 × 51mm)\n\nThickness – 0.063″ (1.6mm)\n\n\nIdeal For\n\nSmall, compact soldered circuit builds\nDIP IC-based projects (fits 14-pin packages)\nTransferring tiny breadboard prototypes to permanent PCBs\n\n\nPackage Contents\n\n3× Perma-Proto Quarter-Sized Breadboard PCBs\n\n\nAlso Consider\n\n\nPerma-Proto Half-Sized PCB – 3-Pack – 30-row version for medium projects\n\nPerma-Proto Full-Sized PCB – 3-Pack – 60-row version for larger projects\n","vendor":"Pololu","product_type":"physical","in_stock":false,"options":[],"variants":[{"id":9168,"title":"Default Title","sku":"PL-2765","price":19.51,"compare_at_price":0.0,"on_sale":false,"in_stock":false,"available_quantity":0,"option1":"Default Title"}]}
