Introducing the New Raspberry Pi PoE+ HAT

What is PoE?

Typically, a Raspberry Pi IoT setup will include a power cable and either Ethernet or WiFi connectivity, but what if both power and low-latency internet connectivity could be combined into the same cable? The Power over Ethernet (PoE) standard does just that, as it allows for devices to negotiate and send various levels of power over the same wires, thus reducing the need for extra cable runs. This can be extremely useful in industrial or smart home applications that need reliable internet connections.

How is the Raspberry Pi PoE+ HAT different?

Launched in the Fall of 2018, the original Raspberry Pi PoE HAT could provide Power over Ethernet to both the Raspberry Pi 3 B+ and 4 models. It used the 802.3af standard that allows for up to 15W to be drawn. When compared to this previous model, the PoE+ HAT can both deliver more power while remaining cooler. Since it implements the 802.3at standard in addition to 803.2af, up to 25W can be used by the Pi.

There's a new Microchip PD70224ILQ bridge rectifier onboard that runs much cooler compared to what was used previously. Additionally, there's a new Bourns planar transformer that utilizes a novel design for a more compact footprint, thus making it slimmer and easier for surface-mount assembly.
