Raspberry Pi PoE+ HAT

Description
The Raspberry Pi PoE+ HAT is designed to replace the existing Raspberry Pi PoE HAT in all new and existing designs. Like the original， the PoE+ HAT allows you to power your Raspberry Pi using Power over Ethernet networks. The PoE+ HAT meets all the requirements of the IEEE 802.3af(802.3at Type 1， PoE+)specifications. This ups the power the network can supply from 15.4 watts(PoE)to 25.5 Watts(PoE+)over CAT5 cable.
No modification to the main Raspberry Pi board is needed for the PoE+ HAT to work but you will need to ensure that your Pi's software is up to date for all functionality to be available. The Raspberry Pi PoE+ HAT is fitted with a small fan that is controlled by the Raspberry Pi via I2C and will turn on and off automatically depending on the temperature of the main processor on your Pi.
Note：There is no Raspberry Pi included with this product. Your desired Pi will need to be purchased separately.
