Late game Quantum Chip module with all mk3 items. If you need more H2 throughput you can copy the "remote demand local supply" ILS towers.
Exports: 1 belt Quantum Chips
Imports: 12 belts Hydrogen* 4 belts Graphene* 4 belts Fire Ice* 4 belts Water 4 belts Titanium 2 belts Titanium Crystal 2 belts Processor *4 Graphene and 2 Hydrogen belts are redundant, as they also come from the Fire Ice. I like redundancy.
