The Pimoroni Mini Black HAT Hack3r breaks out all 40 GPIO pins from your Raspberry Pi while still allowing a HAT or pHAT to sit on top. Connect via the included ribbon cable and access every pin — labelled with function name, BCM number, and physical pin number — for easy debugging, prototyping, or combining a HAT with additional circuits.

Compatible with any Raspberry Pi featuring a 2×20 GPIO header, including the Pi Zero, Pi 3, Pi 4, and Pi 5. Comes fully assembled with headers pre-soldered.
