Eben 6:15: — some wire wrapped round it by a machine and then clamped together, and then some wires coming out. The Raspberry Pi PoE+ HAT is an improved Power over Ethernet add-on board, compatible with any Raspberry Pi with PoE pins (including Raspberry Pi 3B+ and Raspberry Pi 4). The maximum distance of PoE can transmit 100 meters from the switch or hub regardless of where the power is injected due to the ethernet cabling standards. If you wish to extend the maximum distance, you can make use of a PoE extender to further extend the maximum distance of up to 1200 meters.

Removed Raspberry Pi 3 compatibility.

When using PoE, not all devices are compliant. Thus, there is a need of either an injector or splitter for your PoE switch to be able to connect to a non-PoE device.

These expansion boards can be used for everything from general learning to implementing A.I. via Machine Learning. Or you could just build your own Raspberry Pi powered robot to explore the world around us.Thanks to improved thermal design it should run cooler (measured at the hottest point on an uncased board) at any load.

The Raspberry Pi Power over Ethernet HAT is a small accessory for the Raspberry Pi computer. It can only be used with the Raspberry Pi 4 Model B (launched June 2019) and the Raspberry Pi 3 Model B+ (launched March 2018). The PoE HAT allows you to power your Raspberry Pi using Power over Ethernet–enabled networks; for this product to be used, the network it is connected to needs to have power-sourcing equipment installed. Supplied with this productThe spec is that it will supply 20W, but it’s been designed to 25W to give us some engineering margin In addition, PoE voltages are around 15W to 90W where conduits and metal cladding are not required. PoE can be easily set up using a Cat5e or Cat6 ethernet cable without the need of an electrician. There is no startup current limiting, it almost acts like a direct short from Vin to Vout at startup. Some even overshoots the target voltage by a considerable amount.

Eben 3:53: And then there are modes where you put it on the single pairs, and you have to support both of those. Extensive testing over all configurations, operating parameters, and use cases is the only way to minimise the likelihood of releasing a product with a hardware issue. Even relatively simple hardware can end up catching you out by throwing up some unexpected bug or issue. And even the big guys with huge development teams and test labs occasionally mess things up — anyone remember the Pentium FDIV bug?And that's because the first PoE HAT used the 802.3af standard. It only guarantees up to about 13W of power to a "powered device" like the Raspberry Pi.
