Questions
How big is the Magic dial PCB?
It measures 117.1 × 77.2 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Magic dial use?
63 parts, built around the ESP32-C6-WROOM-1-N8, INA240A1QPWRQ1, MAQ430GQE-AEC1-Z and MCP6021T-E/OT-MS. 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 Magic dial KiCad files?
From the 10-Percent-Complete/magic-dial repository on GitHub, at the commit this page was made from: the board is electrical hardware/kicad/magic dial/magic dial.kicad_pcb and its schematic electrical hardware/kicad/magic dial/magic dial.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Magic dial design in my own project?
Its repository states no licence, so its author keeps all rights: ask 10-Percent-Complete before reusing the design.
