Questions
How big is the USBVolumeKnob PCB?
It measures 57.2 × 49.2 mm and has 4 copper layers, 1.6 mm thick.
What parts does the USBVolumeKnob use?
78 parts, built around the SN74LV1T125DBV, SK9822, USBLC6-2SC6 and FTSH-105-01-L-D. 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 USBVolumeKnob KiCad files?
From the Microsparky/usb-vk-hardware repository on GitHub, at the commit this page was made from: the board is USBVolumeKnob.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the USBVolumeKnob design in my own project?
Its repository states no licence, so its author keeps all rights: ask Microsparky before reusing the design.
