Power over Ethernet HAT (B) for Raspberry Pi 3B /4B and 802.3af PoE network

POE HAT for Raspberry Pi

Power Over Ethernet HAT for Raspberry Pi 3B /4B, 802.3af-compliant
(any backward-compatible future versions will be supported as well)

OLED for real-time monitoring temperature, IP, and fan status



The PoE HAT (B) is a 802.3af-compliant Power Over Ethernet accessory for the Raspberry Pi 3B /4B. By using this small HAT and some proper 802.3af-compliant power sourcing equipment, it is possible to provide both network connection and power supply for your Raspberry Pi in only one Ethernet cable.
