Raspberry Pi announces its next generation Power over Ethernet (PoE) HAT, but there is a catch
The latest product to join the Raspberry Pi family is a new Raspberry Pi PoE+ HAT. This version is more powerful, runs cooler and implements the 802.11at PoE+ standard which means it can deliver up to 25W of power.
The previous model will remain in production for a while, and but, like a lot of computer products, it’s affected by the current global semiconductor shortage.
The Raspberry Pi Foundation has announced its new Raspberry Pi PoE+ HAT today, but the company doesn’t currently have any stock in channel and you’ll have to wait until early June before you can buy it.
The table below shows how the old PoE HAT and new PoE+ Hat compare.
