Step 1 – Install the Standoffs

  • Power off the Raspberry Pi 5.
  • Install the four M2.5 brass standoffs onto the Raspberry Pi 5 mounting holes.

Step 2 – Install the GPIO Header

  • Insert the included 2×20 female GPIO header onto the Raspberry Pi 5 GPIO pins.
  • Ensure the header is fully seated.

Step 3 – Connect the PCIe Cable

  • Open the PCIe FPC connector lock on the Raspberry Pi 5.
  • Insert the PCIe cable with the correct orientation.
  • Connect the other end to the 5-Bay SATA Storage Expansion board.
  • Lock both connectors securely.

Important: Incorrect cable orientation may prevent the board from being detected.

Step 4 – Mount the Expansion Board

  • Align the 5-Bay SATA Storage Expansion board with the GPIO header.
  • Carefully lower the board onto the header.
  • Secure the board using the supplied brass nuts.

Step 5 – Install Storage Devices

  • Insert SATA SSDs or HDDs into the SATA slots.
  • Tighten the acrylic side brackets if required.
  • Verify all drives are firmly seated.

Step 6 – Connect Power

Choose one of the following power methods:

Option A – DC Power Input

  • Connect a 12V DC adapter to the 5525(means 5.5mm x 2.5mm) barrel jack.

Option B – Molex Power Input

  • Connect a standard 4-pin Molex power source.

Step 7 – Boot and Verify

  • Power on the system.
  • Boot Raspberry Pi OS or your preferred NAS OS.
  • Verify storage detection:
lsblk
