N-Fuse PoE HAT for the Raspberry Pi 5 also includes mini PCIe or M.2 Key-M/E/B sockets

N-Fuse has designed a PoE HAT for the Raspberry Pi 5 SBC that also serves as a PCIe expansion board thanks to either a mini PCIe socket or an M.2 Key-M, Key-B, or Key-E socket supporting 2230, 2242, or 3042 modules such as SSDs, AI accelerators, or wireless modules.

The SBCPoE RPi5 HAT complies with the latest 802.3bt standard delivering up to 25W with active cooling or 15W with passive cooling. The HAT board still allows users to make use of the 40-pin Raspberry Pi 5 header thanks to a 40-pin Raspberry Pi interposition header.

N-Fuse has tested their HAT with the Intel BE202 Wi-Fi 7 M.2 A/E-Key 2230 card, the Seagate FireCuda 520N SSD M.2 2230 M-Key module, and Huawei 4G LTE ME906E M.2 B-Key 3042 module.  It’s also possible to use USB on the HAT using a USB adapter and a 4-pin cable both seen with other accessories in the photo below.

While the official Raspberry Pi 5 PoE HAT+ is not available just yet, the N-Fuse HAT is not the first PoE HAT for the Raspberry Pi 5, as we previously wrote about Waveshare PoE HAT(F) 802.3af/at-compliant 24W Power-over-Ethernet (PoE) HAT+ board. The N-Fuse solution is different since it also adds a PCIe mPCIe or M.2 socket for expansion.

N-Fuse told CNX Software the SBCPoE RPi5 HAT is a “perfect match for a small home server for file/ video sharing or to run a home automation software like Home Assistant”. The company is taking orders for the PoE HAT for 48 Euros with accessories namely a 40-pin Raspberry Pi interposition header, an FPC cable for PCIe connection, mounting screw(s) for the mini PCIe or M.2 slots, and two nylon standoff spacers.

POE with m.2 b-key (w/SIM) is an interesting hat, the price is out of line for my use case.

It seems there is no transformer, so it should be non-isolated, which is absurd for PoE applications.

The HAT board still allows users to make use of the 40-pin Raspberry Pi 5 header thanks to a 40-pin Raspberry Pi interposition header.

Wouldn’t you need a stacking connector to actually use the header for another HAT? The features quoted say:

Low profile design compatible with many standard RPi enclosures

Sinking 25W into such minimal clearance and airflow seems ill advised.

Waiting for waveshare new version,maybe the price will be lower
