Questions
How big is the Input board PCB?
It measures 270 × 100 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Input board use?
416 parts, built around the 74LVC541AD, AD8599AR, THS4131ID and OPA830ID. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Input board KiCad files?
From the robmacl/ilemt_hw repository on GitHub, at the commit this page was made from: the board is input/input_board.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Input board design in my own project?
Its repository states no licence, so its author keeps all rights: ask robmacl before reusing the design.
