Questions
How big is the Haptic knob PCB?
It measures 23.8 × 36.3 mm and has 4 copper layers, 1.61 mm thick.
What parts does the Haptic knob use?
70 parts, built around the ESP32-S3-WROOM-1U-N4, CH224K, MT2492 and PDRV8311HRRWR. 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 Haptic knob KiCad files?
From the wirano/haptic-knob repository on GitHub, at the commit this page was made from: the board is Hardware/knob_motherboard/haptic-knob.kicad_pcb and its schematic Hardware/knob_LCD/knob_LCD.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Haptic knob design in my own project?
Its repository states no licence, so its author keeps all rights: ask wirano before reusing the design.
