Questions
How big is the Focus Dial PCB?
It measures 50.8 × 0.5 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Focus Dial use?
96 parts, built around the 74AHCT1G125SE, ESP32-WROOM-32E-N4, DRV8313PWPR and MC34063AP. 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 Focus Dial KiCad files?
From the realamoghm/Focus-Dial repository on GitHub, at the commit this page was made from: the board is kicad/focusdial/focusdial.kicad_pcb and its schematic kicad/focusdial/focusdial.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Focus Dial design in my own project?
Its repository states no licence, so its author keeps all rights: ask realamoghm before reusing the design.
