That means the plotting files to make the circuit boards, the list of all the components on them, the positions of all the components. The factory’s going to make the circuit boards and attach most of the components for me. This is good, because many of the components are tiny. The Ilkley prototype is on two boards: a ‘brain’ board that contains the microcontroller and almost all the elect...
