A handy breakout tool that lets you access all 40 GPIO pins while a HAT or pHAT is connected to your Raspberry Pi. Plug in your HAT, connect the ribbon cable to your Pi, and probe, debug, or extend any pin with ease.

Key Features

  • HAT & pHAT Landing Areas – Accepts both form factors with PCB standoffs
  • Full GPIO Access – All 40 pins broken out and clearly labelled
  • Pin Labels – Function name, BCM pin number, and physical pin number printed on PCB
  • 4 Mounting Holes – Secure the board to your workbench or enclosure

Ideal For

  • Debugging HAT and pHAT designs
  • Combining a HAT with breadboard circuits
  • Probing GPIO signals while a HAT is in use
Note: This is the PCB only. Headers, ribbon cable, and rubber feet are not included and must be sourced separately.

Package Contents

  • 1× Mini Black HAT Hack3r PCB

Jargon buster

Plain-language definitions for the technical terms used above.

breakout
A breakout board carries a small or fine-pitched component and brings its connections out to standard, breadboard- and header-friendly pins. Describing a part as a breakout means it can be wired into a project without soldering directly to the component's tiny 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.
Headers
Rows of connector contacts on a fixed pitch (commonly 2.54 mm) used to link a board to a breadboard, jumper wires, or another board. They come as male pin headers and female socket headers; when a module ships with pre-soldered headers it can be used straight away, whereas bare pads require soldering the pins yourself.
PCB
A printed circuit board (PCB) is a board, usually rigid, with etched copper tracks that connect electronic components together without loose wiring. Components are mounted on the board and signals route between them through the copper layout.
pHAT
A smaller add-on board format for Raspberry Pi, similar in idea to a HAT but usually not full-sized. It matters because pHAT compatibility can affect how neatly a board stacks or fits into a Raspberry Pi project.
