樹莓派 Raspberry Pi PoE+ HAT
The Raspberry Pi PoE+ HAT is a new version of the original Raspberry Pi PoE HAT, now with 5V 4A output for the most demanding Raspberry Pi applications! It is designed to replace the original PoE HAT in all new and existing designs and meets all requirements of the IEEE 802.3af (802.3at Type 1) specifications.
The PoE+ HAT is an add-on board for Raspberry Pi boards with PoE (Power over Ethernet) pins i.e. the Raspberry Pi 4 and Raspberry Pi 3B+.
It is used to power a Raspberry Pi via an Ethernet cable, provided that power-sourcing equipment is installed on the Ethernet network. The HAT also includes a fan that will cool the Raspberry Pi processor.
The cooling fan is temperature-controlled, which starts to spin (at a slow speed initially) at 40 degrees. The fan then speeds up as the temperature increases (around every additional 5 degrees) ensuring cool and quiet operation.
Important Notes
- An up to date copy of Raspberry Pi OS (and the latest kernel) is required for this HAT to function correctly. We recommend a fresh install of Raspberry Pi OS.
- Take care when separating the HAT from the Pi. Pull evenly so that it detaches from all the pins at the same rate; do not pull one end of the connector off before the other!
