Questions
How big is the Ctrl pad PCB?
It measures 62.5 × 100 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Ctrl pad use?
23 parts. 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 Ctrl pad KiCad files?
From the Somebud0180/Ctrl_pad repository on GitHub, at the commit this page was made from: the board is PCB/Ctrl_pad.kicad_pcb and its schematic PCB/Ctrl_pad.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Ctrl pad design in my own project?
Its repository states no licence, so its author keeps all rights: ask Somebud0180 before reusing the design.
