1. Suitable for 3B+/4B, and can be used with the official shell of for raspberry pie, without taking up more space2. Support POE Ethernet supply and IEEE802.3 POE network standard3. Fully isolated switch mode supply (SMPS)4. Adopt a more compact component layout scheme, with smaller overall volume and more flexible use5. If there is a PoE router or switch that supports the IEEE802.3af network standard, with this expansion board, only one network cable can be connected to enable for raspberry pie to achieve networking and supply.Model: PoE HAT (E)POE input: 37V~57V DC input output: 5V 2.5A DC outputNetwork standard: support IEEE802.3 POEProduct size: 65.00 x 32.00mmColour:blueMaterial:PCBPackage Contents:1 x Ethernet supply expansion boardOnly the above package content, other products are not included.Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing.
