Compared to its predecessor, the Raspberry Pi PoE+ HAT delivers more power, implementing the 802.3at PoE+ standard; and it runs cooler, thanks to various design improvements. Best of all, we’ve been able to keep the original affordable price of $20.</span></p><p style="margin:0;padding:0px;">&nbsp;</p><p style="margin:0;"><span style="font-family:arial, helvetica, sans-serif;"><span><a href="https://community.element14.com/resized-image/__size/292x217/__key/communityserver-wikis-components-files/00-00-00-01-69/6644.contentimage_5F00_201073.png"><img loading="lazy" alt="image" src="https://community-storage.element14.com/communityserver-components-secureimagefileviewer/communityserver/wikis/components/files/00/00/00/01/69/6644.contentimage_201073.png-292x217.png?sv=2016-05-31&amp;sr=b&amp;sig=G%2FnpcasOl%2BKB7EAaHTI34dyKxFjPZyPzuuZCysEDp%2FM%3D&amp;se=2026-05-16T23%3A59%3A59Z&amp;sp=r&amp;_=gFrQ7shxAeUesn7dShqF6w==" style="max-height: 217px;max-width: 292px;" /></a></span></span></p><p style="margin:0;padding:0px;">&nbsp;</p><p style="margin:0;"><span style="font-family:arial, helvetica, sans-serif;">The original PoE HAT implements the 802.3af standard, and can deliver a guaranteed minimum of 13W to the Raspberry Pi. This is enough to power a Raspberry Pi 4 at maximum load, but not quite enough to power the hungriest USB peripherals at the same time.</span></p><p style="margin:0;"><span style="font-family:arial, helvetica, sans-serif;">The PoE+ HAT implements the 802.3at standard. When used with a compatible switch or injector this means it can deliver up to 25W, as you can see from this comparison table.</span></p><p style="margin:0;padding:0px;">&nbsp;</p><table
