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
