Low-cost passive PoE base unit for powering passive PoE
devices over ethernet. Simply connect your power source to the
injector, and then use an ethernet cable to connect the injector to the
RouterBOARD device. Helps reducing number of wires that lead up the
tower, and in other situations.
For using with RouterBOARDS that support 10-28V PoE powering, input
needs to be at least 18V to accomodate any losses in cables.
