The PoE HAT (C) is a 802.3 af/at-compliant Power Over Ethernet accessory (PoE+) for the Raspberry Pi 3B+/4B. By using this small HAT and some proper 802.3 af/at-compliant power sourcing equipments, it is possible to provide both network connection and power supply for your Raspberry Pi in only one Ethernet cable.
Standard Raspberry Pi 40PIN GPIO header, supports Raspberry Pi 3B+/4B
PoE / PoE+ capability, IEEE 802.3 af/at-compliant
Fully isolated switched-mode power supply (SMPS)
While providing stable power for the Raspberry Pi, there's also a USB-A port for powering extra external device Onboard high speed active cooling fan, better heat dissipation
