he official Raspberry Pi Power over

Ethernet (PoE) HAT allows you to

transmit power over Ethernet

cables to your Raspberry Pi. It’s a

convenient way to get power to your

project – just keep in mind it has a few

limitations. The board is only compatible with

Raspberry Pi 3 B+ and Pi 4, and it won’t fit inside

some cases due to the height of the components.

Also, pin accessibility is difficult when the board is

plugged in, but many applications don’t require the

GPIO pins, and there is a workaround using pass-

through headers. For cooling, the PoE board features

an on-board fan that is controlled via I^2 C. To ensure it

gets the power needed, make sure you are using

802.3af-compliant power-sourcing equipment.

ow, this is a clever little power

supply for your Raspberry Pi. The

Zero2Go Omini will allow your

project to use multiple power

sources. It’s smart enough to be able

to detect the highest voltage and

either increase or decrease the power to a clean 5 V.

There are LEDs that will let you know exactly what is

going on. All you have to do is supply the Zero2Go

with 3.5 to 28 VDC and get building! This is a great

add-on that allows for uninterrupted power from up

to three different power sources.
