Stack up to 5 HATs or pHATs on a single Raspberry Pi with the pHAT Stack from Pimoroni. This solder-yourself kit lets you mix and match multiple add-on boards for dashboard setups, multi-sensor projects, or any build that needs more than one HAT at a time.
The board includes 6 sets of 2×20 pin headers — one connects to your Pi via the included ribbon cable, and the other 5 accept any combination of HATs and pHATs. Use the pHAT Stack configurator to check for pin clashes before combining boards.
Key Features
- 5 HAT/pHAT Slots – Mount up to 5 boards simultaneously
- M2.5 Mounting Holes – For both HAT and pHAT form factors, with labels
- Printed Pinout – BCM numbers and descriptive labels on the board
- Ribbon Cable Connection – Connects to your Pi's GPIO header
- Non-Slip Feet – Rubber feet keep the board stable on your desk
Package Contents
- 1× pHAT Stack PCB
- 6× 2×20 Male GPIO Pin Headers (requires soldering)
- 5× Pairs of Black Brass Standoffs
- 4× Rubber Non-Slip Feet
- 1× 40-Way GPIO Ribbon Cable
Specifications
- Board Dimensions – 162 × 65 × 1.75 mm

Jargon buster
Plain-language definitions for the technical terms used above.
- 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.
- M2.5
- A metric screw thread size with a 2.5 mm nominal diameter. It matters for mounting because screws, standoffs, and holes must use the same size to fit securely without damaging the board.
- 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.
