LAFVIN POE HAT is an Ethernet power-supply expansion board fully compatible with Raspberry Pi 3B+/4B/5.
Compliant with IEEE 802.3af/at standards, it draws power directly from a PoE switch through a single network cable; on-board 12 V/2 A and 5 V/4.5 A independent DC outputs deliver ample power to the Raspberry Pi and peripherals. Application Scenarios:
Pair with any IEEE 802.3af/at PoE router or switch to supply both data and power through one cable, simplifying cable management.

Specifications:
PoE power input: 37 V ~ 57 V DC input
Power output: GPIO header: 5 V 4.5 A (MAX); 2P header: 12 V 2 A (MAX)
Dimensions: 5.9 x 3.9 inch
Weight: 0.22 lb
Network standard: IEEE 802.3af/at PoE

Bill of Materials:
1pcs POE HAT
2pcs 2×2P PoE adapter header
4pcs M2.5×18 brass standoffs
8pcs M2.5×8 black countersunk screws
1pcs Pi5 heatsink kit
1pcsCross-head screwdriver

Precautions:
1. Do not connect power to the Raspberry Pi USB-C port while using the PoE HAT—doing so may damage the board.
2. The PoE HAT works with Raspberry Pi 3B+, 4B and 5, but the official Pi 5 active cooler is compatible only with Raspberry Pi 5.
3. Keep the total continuous power below 25 W; it is recommended to reserve a 20 % margin for stability. If peripherals draw high power, use a switch that supports 802.3at and can supply at least 30 W.
