Smaller pcb + basic usb connector + connector instead of wire. On a large scale it's a good way to drive cost down

I wonder what the benefits of the new CC link compared to the old one. I have both but my ESC is dead.

I think there is a version 0 to that came with the old M25... I'll have to check...

I guess it is just slightly cheaper to make...
