Each board mirrors the layout of a tiny solderless breadboard (plus power rails) with 5-hole connected pads, four power bus rails, and clear silkscreen labelling — perfect for transferring small prototyped circuits to a permanent soldered board.\n\nAll holes are through-plated with a gold finish — pads won't flake off during rework and won't oxidise like bare copper. The unmasked bottom side lets you cut traces when needed, and 1.2mm drill holes accommodate components with larger leads. Two mounting holes on each board allow secure attachment to enclosures.\n\nKey Features (Each Board)\n\n\nQuarter-Size Breadboard Layout – Compact 5-hole pad pattern matching tiny solderless breadboards\n\nThrough-Plated, Gold-Finished – Durable pads that resist oxidation and survive rework\n\nWhite Silkscreen – Row and column markings for easy component placement\n\n4 Power Bus Rails – Side-mounted power and ground distribution\n\n1.2mm Drill Holes – Fits components with larger leads\n\nCuttable Traces – Unmasked bottom side allows easy trace modification\n\n2 Mounting Holes – Secure attachment to project boxes and enclosures\n\n\nIdeal For\n\nSmall, compact soldered circuit builds\nTransferring tiny breadboard prototypes to permanent PCBs\nStocking up on high-quality proto boards for future projects\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":"Adafruit","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":12816,"title":"Default Title","sku":"AF-589","price":16.98,"on_sale":false,"in_stock":true,"available_quantity":4,"option1":"Default Title"}]}
