Passive PoE Cable Set

The Passive PoE Cable Set from Sparkfun is a game-changer for projects that require Ethernet support. It allows data transmission through a local area network and even extends this capacity to the internet. The unique selling point of this product is its ability to use the same cable for both power and data, making it extremely convenient for Ethernet devices.

The Passive PoE Cable Set features a female RJ45 on one side, adapted to a male RJ45 and a 5.5x2.1mm barrel jack connector on the other side. The 'injector' cable includes a female barrel jack connector, while the 'splitter' cable contains a male barrel jack. To use, simply connect the cables at each end of your network cable, plug the male barrel jack from the splitter into your target device, and connect your power adapter to the injector. This setup enables the use of a single cable to provide both power and data for your Ethernet enabled device.

It's important to note that this is not a true 802.3af power injector. Instead, it puts DC onto the unused pair of conductors in the cable. While it works in pairs to transfer power from one end of an Ethernet cable to the other, it may not work with devices that require true 802.3af POE.

With your purchase, you'll receive a set of two cables, offering you great value for your money. The Passive PoE Cable Set is a reliable and efficient solution for powering your Ethernet devices and transmitting data simultaneously.
