The Adafruit Perma-Proto Quarter-Sized Breadboard PCB mirrors the layout of a tiny solderless breadboard with power rails, making it simple to transfer small prototyped circuits to a permanent soldered board. The compact form factor is perfect for small, self-contained projects.

All 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 allow secure attachment to enclosures.

Key Features

• Quarter-Size Breadboard Layout – Compact 5-hole pad pattern matching tiny solderless breadboards
• Through-Plated, Gold-Finished – Durable pads that resist oxidation and survive rework
• White Silkscreen – Row and column markings for easy component placement
• 4 Power Bus Rails – Side-mounted power and ground distribution
• 1.2mm Drill Holes – Fits components with larger leads
• Cuttable Traces – Unmasked bottom side allows easy trace modification
• 2 Mounting Holes – Secure attachment to project boxes and enclosures

Ideal For

• Small, compact soldered circuit builds
• Transferring tiny breadboard prototypes to permanent PCBs
• Space-constrained projects and enclosures
