Many of our favourite Raspberry Pi applications, from garden webcams to industrial controllers, involve putting our products in out-of-the-way locations, where they act as a bridge between the network and the physical world. But the more out-of-the-way the location, the more challenging it is to get power.
PoE offers one solution to this problem, allowing you to send power from Power Sourcing Equipment (PSE) to a Powered Device (PD) over the same four-pair cabling used to carry Ethernet data. All Raspberry Pi SBCs since 2018 have been able to function as a PD, when equipped with an optional PoE or PoE+ HAT.
At the other end of the cable, there are two common types of PSE:
  • A PoE switch combines the network switching and power sourcing functions into a single device.
  • A midspan injector connects to a non-PoE switch, and injects power into the cable while passing through network data in both directions.
Developed with our friends at Microchip, the new Raspberry Pi PoE+ Injector is the perfect way to power your networked Raspberry Pi projects (and other PoE devices) if you’re not lucky enough to have a PoE switch. It supports both the IEEE 802.3af (PoE, 13W) and IEEE 802.11at (PoE+, 25W) standards, and mains voltages between 100V and 240V.

Jargon buster

Plain-language definitions for the technical terms used above.

PoE
Power over Ethernet lets one Ethernet cable carry both network data and electrical power. This is useful when installing a device where running a separate power adaptor would be difficult.
