Power-over-Ethernet (PoE) is a great way to simplify your WisBlock projects. With PoE, a single Ethernet cable delivers both network connection<\/strong> and power<\/strong>, which reduces wiring and makes installations much cleaner. If you want to add PoE support to a WisBlock device, the RAK19018 PoE Module<\/strong> paired with the RAK13800 Ethernet Module<\/strong> is the official solution.<\/p>\n\n\n\n The RAK19018<\/strong> is a small PoE power converter designed specifically for WisBlock. Inside the RAK19018 is a Silvertel Ag9905MT<\/strong> converter, which handles PoE negotiation and converts the high-voltage PoE power down to a safe, regulated 5V<\/strong> output for your WisBlock system.<\/p>\n\n\n\n To use PoE with WisBlock, you will need:<\/p>\n\n\n\n If you have these four things, you\u2019re ready to use PoE<\/p>\n\n\n\n Here\u2019s what happens behind the scenes:<\/p>\n\n\n\n Essentially, the RAK13800 handles communication, while the RAK19018 handles power.<\/p>\n\n\n\n If you\u2019re building an IoT gateway, sensor hub, or anything mounted far from a wall outlet, PoE is a great choice.<\/p>\n\n\n\n Some WisBlock builds don\u2019t consume much power. Fix:<\/strong> Add a small extra load (fan, LED strip, or another WisBlock module) so the PoE source stays active.<\/p>\n\n\n\n Make sure your switch or injector explicitly supports:<\/p>\n\n\n\n Non-standard \u201cpassive PoE\u201d adapters should NOT be used.<\/p>\n\n\n\n Use CAT5 or CAT6 cables in good condition to avoid power drop or unstable PoE negotiation.<\/p>\n\n\n\n A standard PoE-powered WisBlock project will include:<\/p>\n\n\n\n Once everything is connected, your WisBlock will power on automatically as soon as the PoE source supplies power.<\/p>\n\n\n\n The RAK19018<\/strong> makes it easy to add Power-over-Ethernet to your WisBlock project. When paired with the RAK13800 Ethernet Module<\/strong>, it lets your device get both network and power from a single cable. It\u2019s simple, clean, and ideal for remote or hard-to-reach installations.<\/p>\n\n\n\n Just remember:<\/p>\n\n\n\n With these points in mind, adding PoE to your WisBlock project becomes straightforward and reliable.<\/p>\n\n\n\nWhat the RAK19018 Does<\/h2>\n\n\n\n
On its own, it cannot<\/em> connect to Ethernet or accept an Ethernet cable. Instead:<\/p>\n\n\n\n\n
