This PoE (Power over Ethernet) HAT for the Raspberry Pi 4/3B+ allows you to power the Raspberry Pi with a single power-injected Ethernet cable and can be used with both the Raspberry Pi 4 and the Raspberry Pi 3B+. Not compatible with Raspberry Pi 5. The mini size does not occupy the main 40-pin GPIO header and allows it to be housed inside more compact enclosures. The HAT offers your Raspberry Pi 5V 2.5A with a total power budget of 12.5W. You will need Power Supply Equipment (PSE) to supply the PoE signal to the Raspberry Pi via the Ethernet cable, such as a PoE switch or injector. A heatsink is included which should be applied to the board as pictured. It is normal for the board to get hot during normal operating - ensure adequate ventilation to allow the heatsink to do its thang! Updated Model! Following customer feedback, Uctronics have updated this PoE HAT to make it compatible with a wider range of switch brands as well as making it compatible with non-standard 48V PoE power supplies (through 45+, 78-), PoE input 40-57V with multiple protection circuits.
