5G to 2.5Gbps Ethernet board supports RM521F- RM520N- RM500Q-/CN We have added a POE module to this 5G to 2., which can obtain power by connecting to a network device with function. It is recommended to use a switch with function to power the . At the same time, other ports of the switch can directly provide access to PCs and other devices. Aluminum alloy 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.
