The Adafruit Half-size Perma-Proto Raspberry Pi Breadboard PCB Kit combines a prototyping board with a built-in Pi Cobbler breakout. Solder the included 2×13 box header onto the board, connect a 26-pin GPIO ribbon cable (not included), and you get labelled GPIO breakouts alongside a generous half-sized breadboard layout for permanent circuit builds.
Designed to mirror the familiar layout of a half-sized solderless breadboard (30 rows), this PCB makes it easy to transfer your breadboard prototype to a permanent, soldered circuit. The bottom side has the same 5-hole pad pattern as a standard breadboard, with four power bus lines on the sides.
Key Features
- Built-in Pi Cobbler Breakout – All Raspberry Pi GPIO pins labelled and broken out on-board
- Half-Size Breadboard Layout – 30 rows matching standard breadboard pad spacing
- Through-Plated Holes – 1.2 mm diameter drill holes that won't peel off with rework
- Gold-Plated Finish – Resists oxidation unlike bare copper perfboard
- Four Power Bus Lines – Side-mounted power rails for easy VCC and GND distribution
- No Solder Mask on Bottom – Easily cut traces when needed
- Multiple Mounting Holes – Attach to project enclosures securely
- White Silkscreen – Clear labelling on top for easy component placement
Ideal For
- Making breadboard prototypes permanent with soldered connections
- Raspberry Pi GPIO projects needing custom circuitry
- Clean, labelled prototyping with a professional finish
- Mounting in project enclosures
Package Contents
- 1× Half-size Perma-Proto PCB with Pi Cobbler layout
- 1× 2×13 box header (unsoldered)
Jargon buster
Plain-language definitions for the technical terms used above.
- breakout
- A breakout is a small circuit board that makes a tiny or hard-to-solder component easier to connect to with standard pins. It matters because this OLED module can be wired into a microcontroller project without needing to solder directly to the display’s fine contacts.
- GPIO
- General-purpose input/output pins are microcontroller pins you can set in software to read signals, switch devices on and off, or connect to peripherals. The number of GPIO pins matters because it limits how many buttons, LEDs, sensors, and other parts you can wire directly to the board.
- PCB
- A printed circuit board is a rigid board with copper tracks that connect electronic parts without loose wires. For this kit, the PCBs also form the airplane shape, so they are both the circuit base and part of the finished model.
- solderless breadboard
- A reusable board with connected holes for building temporary circuits without soldering. It matters in beginner kits because students can change wiring quickly and safely while learning how components connect.
