Perma-Proto - Half-sized Breadboard Flex-PCB
Best permanent solution for hobbyists transitioning from breadboard prototypes to builds.
The Perma-Proto Half-Sized Breadboard PCB offers a permanent and durable prototyping solution that mirrors the familiar layout of a solderless breadboard. It features clear silkscreen markings for easy component placement and thru-plated holes for enhanced durability and rework. With four power bus lines and gold plating to prevent oxidation, this PCB provides a reliable platform for permanent projects. Two mounting holes allow for secure installation in enclosures, making it ideal for long-term electronic builds.

What customers say
Users overwhelmingly praise the Perma-Proto Half-sized Breadboard Flex-PCB for its unique combination of a familiar layout on a flexible substrate. This design excels in compact, wearable, or curved projects where rigid boards fail. Reviewers consistently highlight the high quality of the flexible material and robust copper traces. The solder pads are noted as surprisingly easy to use, maintaining component reliability. The half size is perfect for miniaturizing projects using Feather or Trinket boards. While priced higher than standard options, customers find the specialized functionality and ability to bridge prototyping to permanent installation in tight spaces offer exceptional value. This Flex-PCB is considered an essential tool for advanced makers needing reliable, flexible circuit solutions.
Know before you buy
The Perma-Proto is designed to mirror the exact layout of a standard half-sized solderless breadboard. This makes it easy to transfer your circuit from a temporary prototype to a permanent build without having to rethink your wiring.
No, the holes are not pre-connected. Unlike a solderless breadboard, you must solder your components and use wire or solder bridges to create the electrical connections between pins.
Yes, the bottom side of the board is designed for easy trace modification. You can cut traces with a hobby knife or add jumper wires to customize the circuit layout as needed.
The gold plating prevents oxidation, which ensures that the copper pads remain easy to solder to, even after the board has been sitting in your parts bin for a long time.
Yes, it features two mounting holes with a 1.2 mm diameter, allowing you to securely screw the board into a project enclosure for a professional, finished look.
