5G to 2.5Gbps Ethernet board supports RM521F- RM520N- RM500Q-/CN We have added a POE module to this 5G to 2.5G router, which can obtain power by connecting to a network device with function. It is recommended to use a switch with function to power the 5G router. At the same time, other ports of the switch can directly provide access to PCs and other devices. Aluminum alloy shell is conducive to heat dissipation, beautiful and practical! It adopts industrial-grade power chips, low power consumption and high energy efficiency design. Under normal circumstances, it only needs power supply from the main USB port to work; the 5A power circuit is combined with a solid capacitor design to stable, reliable and long-term operation of the 5G module.
