Laying out the PCB is like designing a city but where the streets can't touch. The PCB design is well under way and will be finalized in the next few days. Once its complete a small order will be placed to verify the design. The PCBs will be hand populated by us and rigorously tested. They will then go on to be the golden sets used for manufacturing references. The PCB order will take a few weeks to come in so in the meantime the functional prototype will let us develop the software.
