The OELBBBPoE01 is PoE(Power over Ethernet)/PSE (Power Sourcing Equipment) board docked on BBB (BeagleBone Black) with a needed intermediate board. The Battery charger board OELBBBPWR01 is also available for the needed intermediate board. The OELBBBPoE01 provides +48V/15.4W(IEEE802.3af) power sourcing into PoE/PD(Powered Device). The voltage input range is wide from +9V upto +20V, and then DCDC48V converter is mounted in board. The LED1 on board indicates PoE/PD detecting status. The SW1 on board is available for power-off of PoE. Operating temperature range is |15deg.C to +50deg.C. Two ethernet port RJ-45 are mounted on the board.One RJ-45 is for PoE/PD, and another RJ-45 is for non-PoE devices. These two RJ-45 separate PoE power line and ethernet signal line via isolation transformer. When you apply total set with having docked BBB and OELBBBPoE01 and OELBBPWR01, it is very useful and very convenient for user as easy placed IoT/Solar&Li-ion battery/BBB server systems outside installation with PoE devices such as network camera.
