Solder in the included 2×20 box header, connect a 40-pin GPIO cable, and you get labelled pin breakouts alongside 30 rows of breadboard-style prototyping space — ideal for smaller soldered Pi projects.\n\nThe PCB mirrors a standard half-size breadboard layout with 5-hole connected pads, four power bus rails, and clear silkscreen labelling. All holes are through-plated with a gold finish for durability and easy rework — no flaking pads or copper oxidation. Multiple mounting holes let you secure the board in an enclosure.\n\nKey Features\n\n\nBuilt-in Pi Cobbler – 2×20 header position with labelled GPIO breakouts\n\n30-Row Breadboard Layout – Half-size 5-hole pad pattern for compact projects\n\nThrough-Plated, Gold-Finished – Durable pads that resist oxidation and survive rework\n\n1.2mm Drill Holes – Accommodates components with larger leads\n\n4 Power Bus Rails – Side-mounted power and ground distribution\n\nMultiple Mounting Holes – Secure attachment to enclosures and project boxes\n\nCuttable Traces – Unmasked bottom side allows easy trace modification\n\n\n\nNote: Compatible with all modern Raspberry Pi models with 2×20 GPIO headers (Pi B+, A+, Pi 2, 3, 4, 5, Zero, etc.). A 40-pin GPIO ribbon cable is required but not included.\n\n\nIdeal For\n\nCompact soldered Pi projects with fewer components\nSpace-constrained enclosures where a full-size board won't fit\nCustom Raspberry Pi HATs and expansion circuits\n\n\nAlso Consider\n\n\nPerma-Proto 40-Pin Full-Size PCB Kit – 60-row version for larger projects\n\n\nPackage Contents\n\n1× Perma-Proto 40-Pin Half-Size PCB\n1× 2×20 Box Header\n","vendor":"Adafruit","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":4963,"title":"Default Title","sku":"AF-4353","price":13.09,"compare_at_price":0.0,"on_sale":false,"in_stock":true,"available_quantity":46,"option1":"Default Title"}]}
