Address. Other than , everything else is exactly the same.Little knowledge: development board products such as for Raspberry 3B use the address generated by software, which has no effect on communication function and speed; the fixed address has better compatibility in complex network environment and is more conducive to Group companies manage multiple devices, such as binding IP addresses.Colour:black+blueMaterial:PCB+MetalPackage Contents:1 x for NanoPi R4S router (including case)Only the above package content, other products are not included.Note: Light and different displays may the color of the item in the a little different from the real thing. The measurement allowed error is +/- 1-3cm.
