Adafruit Perma-Proto Mint Tin Size Breadboard PCB

The Adafruit Perma-Proto Mint Tin Size Breadboard PCB is shaped to fit perfectly inside a standard Altoids-style mint tin — ideal for compact, enclosed projects. It features 30 rows of 5-hole connected pads in a familiar breadboard layout, plus 80 additional wiring holes around the edges for general connections.

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. Four large mounting holes align with standard mint tin dimensions for secure attachment.

Key Features
