Hi @Yuri_Rage,
I think the interesting features of the CubeRed are redundant main CPUs which could allow improved reliability. There’s definitely a lot of interest in this subject looking at the number of likes on this recent blog post.
The CubeRed is also the only CubePilot autopilot that has ethernet support although I hear there is a serial-to-ethernet board coming soon.
EDIT: BTW one of the CubePilot devs put a lot of effort into adding ethernet support to ArduPilot and I suspect that effort was related to this hardware release
