@Arno thats good to know ;D i imagined one could wire the ATOM and SERVO2s together anyway to pipe the signals. But having a CORE seems fine too so here is the new setup:

its great that the FIRE does have a Battery-Bottom already and i assume this is a very basic setup now. maybe it would be more straight forward to make a single stack but making two interconnected stacks like in the image is surely possible.

Maybe removing the Battery-Modules and get the power right instead. (Though i really like the magnetic charging-connector ;)

okay lets try this setup. from the descriptions it seems to be perfect for a robotic-arm. so just need 6 of these. interconnecting them in a row using the Port.B and Port.C plugs on the Motion-board and Grove cables.
in software the servo-controls get piped from the usb-connection down the Ports through all the ATOMs.

Maybe this sounds reasonable. Sadly the ATOM Motion Kit is currently Out of Stock

edit: in case the servo-controls can not be passed easily/quickly though the row-connection (e.g. the data needs to be received and sent by each ATOM with major delay), it may make sense to connect them using a PaHUB2 and an additional ATOM for parallel distribution?
