Waveshare PCIe To M.2 Adapter with PoE Function for Raspberry Pi 5, NVMe SSD

Combining NVMe storage expansion with PoE on one add-on board means a Pi 5 deployment can get both benefits without stacking two separate HATs on top of each other - fast, reliable NVMe storage for the workload, and the convenience of powering the whole device over the same Ethernet cable carrying its network connection, rather than running a separate power supply to wherever the device is mounted. That combination matters most for a fixed network-connected deployment - a network appliance, a remote sensor hub - where running both power and data cables separately would be an unnecessary complication.
