Raspberry Pi PoE+ HAT Announced With Greater Power Capability For $20
The Raspberry Pi PoE+ HAT will begin shipping next month but was announced this morning. The PoE+ HAT will have shorter manufacturing lead times than the original PoE HAT due to silicon used by the original design being in short supply.
The PoE+ HAT will not only have shorter lead times but is also superior and priced the same ($20 USD) as the original. Besides supporting 802.3af as with the original PoE HAT, the plus model also adds support for 802.3at. In conjunction with supported 802.3at switches, the PoE+ HAT can now provide a maximum power output of 25.5 Watts, which is plenty for the Raspberry Pi 4 and accessories. The original model had a maximum power output of 15.4 Watts which was enough for the Raspberry Pi 4 itself but not for attached accessories in some instances.
The Raspberry Pi PoE+ HAT is much the same but also has current sense support and a planar transformer design rather than wire-wound. Heat dissipation with the PoE+ HAT should be better too but still requires a fan.
