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.
SBCPoE RPi5 HAT specifications:
- Power Supply
- IEEE 802.3af/at/bt compliant
- Overload protection
- 25W power delivery with active cooling, 15W without active cooling
Output current up to 5A - 5V output via optional 2.54mm pin header
- High efficiency (> 85%) enabled by active MOSFET bridge rectifier
- Short-Circuit Duration – infinity
- PCIe expansion (one or the other)
- Mini PCIe socket
- M.2 B-Key socket and Nano SIM card slot
- M.2 E-Key socket
- M.2 M-Key socket
- M.2 sockets support 2230, 2242, and 3042 modules
- Misc
- Power LED, PCIe activity LED
- Low profile design compatible with many standard RPi enclosures
- Allows for passive cooling of the Broadcom BCM2712 SoC
- USB add-in card option through wire to USB port
- Dimensions
- Mini PCIe model – 68 x 14 x 56.7 mm
- M.2 models – 65 x 14 x 56.7 mm
- Weight – 75 grams
- Temperature Range (without active cooling)
- -40 to +40°C maximum
- -40 to +30°C recommended
- Certifications – CE, UK CA
- Materials – RoHS, REACH
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.
Jean-Luc started CNX Software in 2010 as a part-time endeavor, before quitting his job as a software engineering manager, and starting to write daily news, and reviews full time later in 2011.

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.
Wouldn’t you need a stacking connector to actually use the header for another HAT? The features quoted say:
Sinking 25W into such minimal clearance and airflow seems ill advised.
Waiting for waveshare new version,maybe the price will be lower
