Raspberry Pi launches affordable Power-over-Ethernet Injector for users

In March 2025, the Raspberry Pi team introduced a Power-over-Ethernet Injector, targeting users who want to enhance their networking capabilities without needing a PoE-capable switch. This technology allows power and data to be transmitted through Ethernet cables, which is especially beneficial in settings where accessing power outlets is challenging. The newly released Raspberry Pi PoE+ Injector supports IEEE 802.3af (providing 13 W) and IEEE 802.11at (providing 25 W) standards and is compatible with mains voltages ranging from 100 V to 240 V. Users are to provide their own mains lead and RJ45 connectors to utilize the Injector effectively. Power-over-Ethernet technology has grown in popularity, particularly in home lab environments. However, its utilization hinges on having appropriate network switches that support PoE. The Raspberry Pi Injector circumvents the need for such switches, making it accessible for users who may lack the necessary infrastructure. This release comes after previous challenges Raspberry Pi faced with the Pi 3 Model B+ Power-over-Ethernet adapter, which had significant power issues related to USB ports traced back to hardware problems not identified before the product was released. Despite this setback, Raspberry Pi has continued to innovate in the realm of PoE technology. While the PoE Injector is ready for use, Raspberry Pi also addressed the absence of the official PoE+ HAT+ for the Raspberry Pi 5 during the announcement. This accessory is crucial for devices to draw power from PoE sources but was not included in the latest release. Eben Upton, a prominent figure at Raspberry Pi, explained that the delay in producing the HAT was primarily due to engineering challenges, notably the introduction of a planar transformer on a custom PCB, enhancing efficiency while reducing components. Presently, users still have access to third-party options or splitters that can facilitate USB-C power connections. Overall, the launch of the Raspberry Pi PoE+ Injector signifies a significant step for users looking to leverage Power-over-Ethernet technology in various applications. With readily available, affordable tools, Raspberry Pi aims to simplify networking capabilities for a broader audience, providing a flexible solution to power devices remotely. This product not only addresses prior concerns with the company’s earlier offerings but also emphasizes their commitment to evolving their product lineup amidst ongoing technological developments.
