Questions
How big is the Simple PCB?
It measures 72.5 × 50 mm and has 4 copper layers, 1.61 mm thick.
What parts does the Simple use?
78 parts, built around the OPA172ID, OP07, OPA145ID and NE5534D. 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 Simple KiCad files?
From the Atmelfan/src-multislope-adc repository on GitHub, at the commit this page was made from: the board is examples/simple.kicad_pcb and its schematic examples/simple.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Simple design in my own project?
Its repository states no licence, so its author keeps all rights: ask Atmelfan before reusing the design.
