It requires a (yellow) belt of iron and half a belt of copper. Of course, you can setup a small red science line first and then add the rest later. Aesthetically I dislike the cable plants for not being in the grid, but it needs the full circuit production to make enough inserters. It overproduces belts (since they are 2/0.5s instead of 1) so you could buffer them to pick them up easily (but I think I should build a small centralized "store" anyway to prevent too much time wasted running around to pick things up)
It would also be nice to not have the UG belt, but I don't see a way of using this setup without crossing the iron line under the copper line or assemblers.
(Edit: I just realized that using a joint red/green line will make it more difficult to add some buffering, so maybe I should make the setup 1 tile wider and output the separate belts to be joined after the buffering...)
