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
