ALLNET Rock Pi PoE Hat / Shield 802.3AT (RockPoEF4)

The ALLNET Rock Pi PoE Hat / Shield 802.3AT (RockPoEF4) is a Power over Ethernet (PoE) expansion board designed specifically for the Radxa Rock Pi 4 series single-board computers. It enables both power and data transmission over a single Ethernet cable, simplifying installation and reducing cable clutter. Compliant with IEEE 802.3at (PoE+) standard, it delivers up to 20W of power to the Rock Pi, making it ideal for applications where a separate power supply is inconvenient or unavailable.

Advantages

This PoE Hat eliminates the need for an external power adapter, allowing for cleaner and more flexible deployments. It features an integrated PWM-controlled fan for active cooling, ensuring stable performance even under heavy loads. The shield supports Gigabit Ethernet data pass-through, maintaining high-speed network connectivity. With overcurrent and short-circuit protection, it safeguards both the Hat and the connected Rock Pi board.
