Pimoroni pHAT Stack for Raspberry Pi

The Pimoroni pHAT Stack is an expansive breakout PCB that lets you connect up to five HATs, pHATs, or bonnets to a single Raspberry Pi. With six sets of 2×20 pin headers — one for your Pi and five for add-on boards — the combinations are virtually endless.

It's perfect for projects that combine multiple boards, such as pairing a display (OLED Bonnet or Inky pHAT) with a sensor board (Enviro pHAT) to show live readings. Before stacking, check that your boards don't have GPIO pin clashes using the Raspberry Pi pinout configurator at pinout.xyz.

Key Features

• 5 Add-On Slots – Connect up to five HATs, pHATs, or bonnets simultaneously
• Pre-Soldered Headers – Six sets of 2×20 male GPIO pins already soldered in place
• HAT & pHAT Mounting Holes – M2.5 mounting holes with labels for each slot
• Printed Pinout – On-board reference with BCM numbers and pin labels
• Fully Assembled – Ready to use out of the box

Package Contents

• 1× pHAT Stack PCB (with 6× 2×20 male GPIO pins pre-soldered)
