The PoE/ETH/USB HUB HAT is a PoE (Power over Ethernet) USB HUB HAT compatible with Raspberry Pi Zero. Key benefits Power and network over a single Ethernet cable when used with 802.3af compliant power sourcing equipment, reducing wiring and clutter. Three extended USB ports provide additional peripheral connectivity for USB devices such as storage, keyboards, mice, or sensors. Compact HAT design that fits Raspberry Pi Zero, enabling a small form factor for embedded or spacelimited projects. Reliable 10/100 Mbps Ethernet through the RTL8152B controller with autonegotiation on the RJ45 port. Simple integration with a Raspberry Pi Zero for convenient headless deployment or compact setups. What it is and how it works A compact PoE/ETH/USB HUB HAT that attaches to a Raspberry Pi Zero to deliver both network access and power via a single Ethernet cable (when used with a proper 802.3af PoE power source). The RTL8152B Ethernet chip provides a 10/100 Mbps RJ45 connection with automatic speed negotiation. The HAT adds three extended USB ports, expanding the Pi Zero's peripheral options without needing separate USB power adapters for the Pi. Compatibility and requirements Compatible with Raspberry Pi Zero (HAT form factor). Requires an 802.3afcompliant power sourcing equipment (PoE supply) to deliver power through the Ethernet cable. Uses a standard RJ45 Ethernet connection for data and power delivery when PoE is used. Specifications at a glance Ethernet controller: RTL8152B Ethernet speed: 10/100 Mbps with autonegotiation on RJ45 USB ports: 3 extended USB ports Power delivery: PoE via 802.3af compliant equipment Form factor: PoE/ETH/USB HUB HAT for Raspberry Pi Zero Function: Provides network connection and power to Raspberry Pi Zero over a single Ethernet cable Use scenarios Remote or headless Raspberry Pi Zero deployment: Deploy in field or a remote site where a single PoE Ethernet cable supplies both power and network, simplifying installation and reducing wiring. Compact projects with multiple peripherals: Use the three extended USB ports to connect storage, keyboards, sensors, or other USB devices while keeping the power and network connection through one cable. Education, labs, and demonstrations: Set up quickly in classrooms or labs where clean wiring is important and PoE provides a straightforward power source for Raspberry Pi Zero demonstrations. Notes The device relies on 802.3af PoE equipment to supply power; ensure your setup includes a PoEcapable switch, injector, or other power sourcing equipment. This HAT leverages the RTL8152B Ethernet controller for reliable 10/100 Mbps connectivity and uses a standard RJ45 interface.
