Mint-tin prototyping board

The Adafruit Perma-Proto Mint Tin board is a single-piece PCB designed to fit inside a standard Altoids-sized mint tin. It provides a permanent solderable platform for moving a circuit from a solderless breadboard into a compact enclosure. The layout mirrors a half-size breadboard so component placement translates directly.

Makers finalising pocket-sized builds

This board suits hobbyists and engineers who want a labelled, durable perf-board for projects that must live inside a mint tin. The 30 rows of five-hole pads and four marked power rails speed up transfer work. Builders needing a larger prototyping area, a different form factor, or surface-mount pads should look at other options.

Silkscreen labels and drilled mounting holes

White silkscreen on the top side reproduces familiar breadboard markings to reduce wiring errors during transfer. The bottom side has no solder mask, allowing traces to be cut easily when a circuit change is needed. Four 3.0 mm mounting holes on a 1.65-inch square pattern secure the board inside the tin.

Questions about this item

What size mint tin is the 92 mm x 57 mm board designed to fit?

The PCB matches the dimensions of a standard Altoids mint tin, measuring 3.6 inches by 2.24 inches.

Will the 1.2 mm drill holes accept the thicker leads from older through-hole components I have?

Yes, the 1.2 mm holes are sized to accommodate parts with larger leads that might not fit standard perf boards.

How can I verify the power rails are connected correctly after soldering?

Check continuity between the positive and negative marked pads along each of the four side bus lines to confirm the intended connections.
