Banana Pi PoE HAT-R1 - Power over Ethernet Add-On for BPI-M4 and Selected BPI-M6 BuildsThe Banana Pi PoE HAT-R1 is a board-level power accessory intended for Banana Pi single board computer deployments that benefit from single-cable installation. For the Banana Pi BPI-M4, the official Banana Pi hardware page explicitly lists PoE function support and identifies PoE as one of the board's supported power sources. This makes the PoE HAT-R1 a practical accessory for wall-mounted nodes, compact control cabinets, and other builds where reducing separate power wiring is more important than adding new computing features.For the Banana Pi BPI-M6, the official materials confirm Ethernet networking and a 40-pin expansion header, but that should be treated as host-side context rather than standalone proof of PoE HAT-R1 compatibility. The BPI-M6 getting started guide and the official BPI-M6 store page position the M6 as a Gigabit Ethernet SBC with a standard 40-pin expansion header, while the PoE HAT-R1 SKU should be treated as confirmed for BPI-M4 and suitable for selected BPI-M6 builds only after header, power-path, and mechanical compatibility are verified.If you are building a VS680-based system, you can also pair this accessory listing with the Banana Pi BPI-M6 Synaptics VS680. For PoE-focused Banana Pi workflows in other product families, OpenELAB also carries the BPI-5400B PoE Module and the Banana Pi BPI-F2P for industrial gateway style deployments.Technical Specifications Parameter Value Product Type Power over Ethernet add-on HAT / accessory board Product Name POE HAT-R1 Target Boards Banana Pi BPI-M4; selected BPI-M6 builds only after compatibility, header, and enclosure confirmation BPI-M4 Official Power Note Banana Pi documents BPI-M4 as supporting power by USB Type-C or PoE BPI-M6 Host Platform Synaptics VS680 SBC with Gigabit Ethernet and 40-pin header BPI-M4 Host Platform Realtek RTD1395 SBC with Ethernet, Wi-Fi, and 40-pin GPIO header Host Expansion Context 40-pin GPIO and power header on supported Banana Pi boards Network Dependency Designed for Ethernet-connected Banana Pi deployments Primary Function Reduce separate DC wiring in supported SBC installations Typical Deployment Kiosk, media node, embedded controller, edge device, or industrial cabinet Host Power Alternative BPI-M4 uses 5V input by USB Type-C; BPI-M6 uses 5V 3A Type-C as standard direct power input Software Compatibility Board-level power accessory; follows the operating system support of the host board Board Family Size Context BPI-M4 and BPI-M6 are both documented at 92 x 60 mm form factor Install Considerations Confirm enclosure clearance, header alignment, and switch or injector compatibility before deployment Board Layout & Label Guide PoE HAT body: the accessory mounts as an add-on board rather than replacing the host SBC. 40-pin Host Header Interface - Installation depends on matching the host board header geometry, power path, and mechanical clearance; verify this especially for BPI-M6 builds. Ethernet-driven power workflow: this accessory is intended for Ethernet-connected installations where power is delivered through the network path. Host board RJ45 area: keep the network side unobstructed because PoE deployment depends on stable Ethernet connectivity. USB Type-C fallback path: supported hosts can still be powered by their normal Type-C input during bench testing or firmware bring-up. Case clearance zone: verify that standoffs, lids, and heatsinks do not interfere with the HAT once installed. Thermal envelope: when the host board is used in enclosed spaces, leave airflow above the SBC and around the add-on board. Cable routing path: plan Ethernet cable bend radius so the add-on board and host header are not stressed during installation. Packing List 1 x POE HAT-R1 accessory board FAQQ: What does this product add to a Banana Pi build?A: It is sold as a PoE add-on accessory for supported Banana Pi boards, allowing the host system to be deployed in installations where Ethernet-based power delivery is preferred.Q: Which boards is it intended for?A: This SKU is sold first as a Banana Pi BPI-M4 PoE accessory; for BPI-M6, treat it as selected-build compatible only after checking header alignment, power path, and enclosure clearance.Q: Is PoE support officially documented on the BPI-M4?A: Yes. The official Banana Pi BPI-M4 hardware page explicitly lists PoE function support and includes PoE in the documented power-source options.Q: Is the BPI-M6 a compatible host form factor for this type of accessory?A: The official BPI-M6 documentation shows Gigabit Ethernet and a 40-pin header, but that is host-board context, not complete proof that every BPI-M6 build accepts this HAT without verification.Q: Does this accessory change CPU, memory, or storage performance?A: No. It is a power and deployment accessory, not a compute upgrade.Q: Can I still power the board directly during setup?A: Yes. Both host board families keep their normal direct-power workflow for bench setup and troubleshooting.Q: Should I verify case fit before final installation?A: Yes. Check header height, heatsink clearance, and Ethernet cable routing before you close the enclosure.Q: Should I treat this as a generic PoE module for other boards?A: No. This listing should be treated as a board-specific accessory for BPI-M4 and verified selected BPI-M6 builds unless your mechanical layout and power path have been verified separately.
