PoE Injector Passive Cable Set
Connecting your IOT project to the device using a passive PoE injector cable is now very easy. Very useful for projects that have an Ethernet connection and also require a power cable. This is an ideal solution to get rid of cable clutter. There is an official Power over Ethernet standard that allows devices and routers to enable 48VDC power lines on unused Ethernet pins (4.5 and 7.8), but PoE is expensive and requires a dedicated router. For DIY projects, please consider using these cables instead. This cable has an Ethernet plug and port and a 2.1 mm jack. When you plug in a power supply (like a 9VDC adapter), the injector is connected to the power adapter so pins 4 and 5 are connected to power adapter ground and pins 7 and 8 have positive 9VDC. The other cable is doing the opposite, separating pins 4.5 and 7.8 and connects them to a 2.1mm DC drum plug. You can then use DC plugs to power your project as if it were directly connected to the adapter. Since these cables use pins 4, 5, 7 and 8 to transmit power, you cannot use them in Gigabit Ethernet (these pins are used by Gigabit routers), but your device and router must fall back to 10/100.
