OUTPUT: Yello, Red and Blue Belts, Underground Belt and Splitters </br> INPUT: Iron plates (2 belts)</br> INPUT: Green & Red Circuits (on one belt)
Made this Blueprint because I couldn't find a beginner bp for belts and those I found did not have the assembling machine bp named with the belts. It's based on another bp I found online but I don't remember, who it was.
Replace Medium electric pole with small ones if you don't have them yet.
