Questions
How big is the High res scrollwheel PCB?
It measures 59 × 44 mm and has 2 copper layers, 1.6 mm thick.
What parts does the High res scrollwheel use?
38 parts, built around the AMS1117-3.3 and USBLC6-2SC6. 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 High res scrollwheel KiCad files?
From the Jonathan-C-L/high-res-scrollwheel repository on GitHub, at the commit this page was made from: the board is hardware/high-res-scrollwheel/high-res-scrollwheel.kicad_pcb and its schematic hardware/high-res-scrollwheel/high-res-scrollwheel.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the High res scrollwheel design in my own project?
Its repository states no licence, so its author keeps all rights: ask Jonathan-C-L before reusing the design.
