A Diamondistributor with 16 (2^4) inputs and outputs, in 2 (2^1) layers. Recommended to use inputs and outputs in order by distance of their ends from a perpendicular bisector. That is, if they are facing north, then use the northmost OR southmost belts first. Place two of this next to each other for (part of) a T5L1, or stack two of this for (part of) a T5L2.
