Chosen Solution

I’ve been given a Retina MacBook i7/16/512 laptop with a broken screen and keyboard (previous user had it docked permanently. I’m curious if its a the 2016 -> 2017 logic boards are a direct swap as this could be an awesome upgrade to keep me going on a perfectly good 2016 chassis?

The connectors and the connecting parts are the same between these two systems. So it does appear to be compatible. Given the costs I think you can find a used system for less than swapping out the logic board, besides availability of the part.
