MCDODO PoE+ NVMe Expansion Board Raspberry Pi 5 5V 4.5A 2230 2242 2260 2280

PoE+ power and NVMe for Pi 5

This expansion board adds 802.3 at Power over Ethernet and an M.2 M-Key NVMe slot to a Raspberry Pi 5. It delivers 5V 4.5A to the Pi through the Ethernet cable, removing the need for a separate USB-C power adapter. The board targets builders who want a single-cable deployment for always-on projects such as Home Assistant, light servers or small Pi clusters. A compatible PoE+ switch or injector is required to power the system.

Single-cable build integration

The HAT draws power and data from one Ethernet connection, freeing desk space and cabinet ports from extra power bricks and storage cables. It mounts directly on the Pi 5 GPIO header and exposes an M.2 M-Key slot for NVMe drives, so the microSD card can be replaced entirely. Builders who need SATA or AHCI M.2 drives cannot use this board, and no SSD is included in the package.

Four NVMe form factors supported

The slot accepts 2230, 2242, 2260 and 2280 NVMe SSDs, giving flexibility to choose capacity and physical length that suit the enclosure. Boot times, database access and long-term reliability improve over microSD storage for typical IoT and NAS workloads. The 5V 4.5A PoE power path is sized for the Pi 5 plus a single NVMe drive; adding high-power peripherals or a second storage device would exceed the available headroom.
