Questions
How big is the Low profile with trackball PCB?
It measures 228.8 × 76.2 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Low profile with trackball use?
138 parts, built around the RP2040, W25Q16JVUXIQ, SMF05CT1G and XC6206P332MR. 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 Low profile with trackball KiCad files?
From the ryoo14/rhyn47 repository on GitHub, at the commit this page was made from: the board is low-profile-with-trackball/pcb/low-profile-with-trackball/low-profile-with-trackball.kicad_pcb and its schematic low-profile-with-trackball/pcb/low-profile-with-trackball/low-profile-with-trackball.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Low profile with trackball design in my own project?
Its repository states no licence, so its author keeps all rights: ask ryoo14 before reusing the design.
