==Overview==
==Overview==


''' PoE HAT (C)''' is a Power over Ethernet (PoE+) expansion board for'''  Raspberry Pi 3B+/4B''' , supporting'''  IEEE 802.3af/at ''' network standard. If you have a PoE router or switch that supports the IEEE 802.3af/at network standard, then take me and you '''only need a network cable '''to connect to your Raspberry Pi to achieve networking and power supply.
The''' PoE HAT (C) ''' is a'''  Power over Ethernet (PoE+) expansion board'''  designed specifically for'''  Raspberry Pi 3B+ and 4B''' . When used with'''  802.3af/at ''' compliant power sourcing equipment (such as PoE switches or routers), it delivers ''' both network connectivity and power supply''' through a single Ethernet cable, eliminating the need for an additional power adapter and simplifying cabling for IoT, cluster, and industrial deployments.

==Features==
 
* Based on standard''' Raspberry Pi 40-pin GPIO interface''', compatible with '''Raspberry Pi 3B+/4B'''; stackable pass-through design supports mounting '''additional HATs'''
* Based on Raspberry Pi '''40pin GPIO''' interface, suitable for '''Raspberry Pi 3B+/4B.'''
* Supports '''PoE power over Ethernet''', compliant with IEEE 802.3af/at PoE/PoE+ network standards
* Support''' PoE power over Ethernet''', support IEEE 802.3af/at PoE/PoE+ network standard.
* Adopts fully isolated switch mode power supply (SMPS)
* Using a fully''' isolated switch mode power supply''' (SMPS).
* Onboard original MP8676 buck chip, providing up to''' 4.5A '''total output for Raspberry Pi mainboard and USB-A port
* Onboard USB Type A interface, while satisfying the stable power supply of the Raspberry Pi, can also '''supply power to additional external devices.''' (5V USB-A Provides Up To 4A Output;MAX 25W For 12V+5V Total Output Power)
* Onboard USB Type-A interface: ensures stable power supply for Raspberry Pi while supplying power for additional external devices, with 5V 4A maximum output  <span style="color:red">'''(power only, no data transmission)'''</span>
* Onboard '''high-speed active cooling fan '''for better heat dissipation.
* Onboard 2-pin 12V header with 12V 2A maximum output (2.54mm Dupont)
* Onboard MP8676 Buck Chip:Incorporates Original Voltage Buck Chip Providing Up To 4.5A Output For Raspberry Pi And USB-A Port
* Equipped with high-speed active cooling fan for better heat dissipation (Fan switch: EN for auto running on powerup, DIS for disabling the fan)
 
* <span style="color:red">Please note: '''25W maximum''' combined output power for 12V pin header and 5V USB-A port</span>
