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 metal pins used to plug a module into a breadboard or connect it with jumper wires. Pre-soldered headers make the module easier to use straight away without needing to solder 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 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.
- 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.
