Raspberry Pi 5 N05 M.2 2242 PCIe NVMe Top Extension Adapter

Raspberry Pi 5 N05 M.2 2242 PCIe NVMe Top Extension Adapter connects an M.2 2242 NVMe SSD to the Raspberry Pi 5 using the Pi 5's own PCIe interface, rather than a USB caddy.

What "2242" and "top-mounted" mean for you

• M.2 2242 is the SSD module size the board accepts — a short M.2 stick roughly 42mm long. Longer or shorter M.2 formats aren't what this board is built for.
• Top-mounted means the adapter sits on top of the Pi 5 as an extension board, rather than as a separate carrier or HAT underneath. Plan enclosure clearance around that added height.
• PCIe interface: the board uses the Pi 5's PCIe connector directly, which is how it talks to the NVMe drive — no USB bridge involved.

What it's for

The listing points to embedded systems, edge computing, and development platforms — projects where the Pi 5 needs faster, PCIe-based storage instead of, or alongside, a microSD card. Typical uses include network storage nodes, data logging, and development environments that need higher storage throughput.

Before you order

Check that your SSD is the 2242 length — this adapter is specific to that module size. Also confirm the board's mounting will fit whatever case or bracket you're building the Pi 5 into, since it extends upward from the board.

The board is designed to keep standard Raspberry Pi 5 mounting arrangements intact, so it should sit alongside typical Pi 5 mounting points in a custom enclosure.
