***** **********Best Quality Guranteed. *****What is it - A PoE splitter to split the PoE+ signal ( 802.3 at) into gigabit Ethernet and 5V/4A DC power, which could be adapted to USB-C or 5521 barrel port. *****What is PoE Deliver power and data with a single Ethernet cable for fewer wall plugs and messed cables. Extend powerline to where no AC outlets are nearby, up to 300 feet away from the power source. *****Why PoE splitter A cost-effective way to add plug-and-play PoE support to devices with a 5V power-hungry device, such as the Jetson Nano with a barrel port or the Raspberry Pi 4 with a USB-C port.
*****What else needed - You need an IEEE 802.3 at compliant PoE+ switch or injector to serve as the PSE (Power Source Equipment) and an Ethernet cable with PoE+ signal to feed the splitter. *****Note 1) This splitter does not support other voltages than 5V or QC/PD protocols. 2)This splitter needs PoE+ ( 802.3 at) devices to unleash its full power. 3) Just put the split Ethernet aside if you do
