Questions
How big is the Control PCB?
It measures 39.6 × 99.1 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Control use?
38 parts, built around the TL072 and SMF16A. 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 Control KiCad files?
From the Antonio-Ciociola/esper repository on GitHub, at the commit this page was made from: the board is pcb/esper_v1/control.kicad_pcb and its schematic pcb/esper_v1/Input.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Control design in my own project?
Its repository states no licence, so its author keeps all rights: ask Antonio-Ciociola before reusing the design.
