With any Raspberry Pi project you may reach a step that involves 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 single board computers since 2018 have been able to function as a PoE device, when equipped with an optional PoE or PoE+ HAT.
If you happen to have a all-in-one PoE switch, you could use that as the power and network supply for multiple devices. But if you don't want a switch, or if you just have one device, or maybe you can't change the upstream swtitch, then you can use a midspan injector like this one!
The new Raspberry Pi PoE+ Injector is the perfect way to power your networked Raspberry Pi projects (and other PoE devices) without needing 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.
A 'standard' IEC power cable is not included, you almost certainly have many in your cable-box or in the IT department's cable collection. You'll also need an Ethernet cable!
