This PoE HAT can be used with raspberry pi 3 model B+ and raspberry pi 4 model B (Raspberry Pi boards are not included).
^^ Output Power: DC 5V ( 2.5A Max);
Total Power Budget: 12.5W; IEEE 802.3 af Compliant ^^
Smaller Size: Save more space, no hassle to assemble with the Raspberry Pi and mount on the rackmount.
^^ Effective Cooling Fans: the 25mm25mm brushless cooling fans make your device keep working at the proper temperature.
^^ NOTE: The network switch or power sourcing equipment (PSE) is needed to supply the PoE signal, and they must be compliant with the IEEE 802.3 af or 802.3 at PoE standard, particularly section 33.4. 1 with regards to PSE electrical isolation of the leads. For the non-isolated switch, such as some Ubiquiti switches can not provide proper isolation, they can only work with CAT 5E and CAT 6E network cable.
