PoE+ HAT is a Power over Ethernet (PoE) expansion board suitable for Raspberry Pi 3B+/4B. It has better heat dissipation and supports 802.3af/at network standard. It can provide 5V DC/4A with more power, which is enough At the same time, it can supply power to the Raspberry Pi 3B+/4 and other peripheral devices under the maximum load.If you have a PoE router or switch that supports the 802.3af network standard, you only need a network cable to connect and supply power to your Raspberry Pi.Larger cooling air volume, more efficient heat dissipation, equipped with 25X25mm controllable brushless cooling fan, providing 2.2CFM larger cooling air volume.Simple installation, suitable for Raspberry Pi 3B+/4B.Support PoE Power over Ethernet and support 802.3af/at network standard.Power supply:5Vdc +/- 5%, powered by Raspberry Pi via USB portProvide 5Vdc via DC power jack or XH2.5 connector for additional power supply for SSDPorts and connectors:USB socket-USB 3.0 Type A x1Power input jack 5.5 * 2.5mm x1XH2.54 SSD power input connector x167-pin M.2 connector P = 0.5mm, H3.2mm, key B x1Colour: greenMaterial: PCB+metalSize: 65x56.5mmPackage Contents:1 * PoE+ HAT expansion boardOnly the above package content, other products are not included.Note: Light shooting and different displays may cause the color of the item in the picture a little different from the real thing.
