IN BRIEF
The Raspberry Pi PoE+ HAT is an update on the 2018 model, which fixes the annoying fan noise and coil whine but has its own issues that need to be resolved. It has an improved power output that’s enough to power even the hungry Raspberry Pi 4.
March 2018 saw the release of the Raspberry Pi 3B+, which featured new PoE header pins. It wasn’t until August of that year that we saw the PoE HAT go on general sale. PoE is Power over Ethernet and it provides a one-cable solution for powering your Pi and connecting to a network.
The original PoE HAT worked, but the first batch of units had an annoying “buzzing sound” hardware fault that led to Raspberry Pi offering a replacement scheme. Fast forward to 2021 and Raspberry Pi has released an update to the original model designed with the Raspberry Pi 4 in mind. Yet while it fixes some issues, it creates some new ones, too.
