Hardware needed:
Raspberry Pi PoE HAT (this product)
A Raspberry Pi 3 Model B+ (not included)
An Ethernet cable (not included)
Power-sourcing equipment for a 802.3af Power over Ethernet network (not included)

Hardware connection:
Before installing the PoE HAT, you must attach the supplied spacers in the four corners of the board.
Connect the PoE HAT to the Raspberry Pi 40pin and 4pin PoE interfaces.
Once the PoE HAT board is connected, you can power the Raspberry Pi through its RJ45 network connector.
When unplugging the PoE HAT, pull evenly to make the module smoothly detach from the Raspberry Pi pin, avoiding the pin header

Note:
Can only be powered by PoE devices that comply with the 802.3af standard.
The external power source used by the Raspberry Pi should comply with the relevant regulations and standards of the target country.
The connection of incompatible devices to the GPIO connection may affect compliance and result in damage to the unit.
Should be operated in a well ventilated environment, if used inside a case, the case should not be covered.
It should be placed on a smooth insulating surface during use and should not be in contact with conductive objects.
Do not block or block the fan, do not insert anything in the fan.
Do not expose this product to water, moisture or high temperatures. This product is designed to operate at normal room temperature.
Take care whilst handling to avoid mechanical or electrical damage to the printed circuit board and connectors.
Avoid handling the printed circuit board whilst it is powered and only handle by the edges to minimise the risk of electrostatic discharge damage.
