Questions
How big is the DetentOne PCB?
It measures 150 × 85 mm and has 4 copper layers, 1.6 mm thick.
What parts does the DetentOne use?
98 parts, built around the ESP32-S3-WROOM-1U-N16R8, PCA9554ARGVR, SGM2050XTRL20G/TR and XY-GH1.25-7A61. 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 DetentOne KiCad files?
From the alislaboratory/detentOne repository on GitHub, at the commit this page was made from: the board is PCB/detentOne.kicad_pcb and its schematic PCB/Encoder.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the DetentOne design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
