Questions
How big is the Left PCB?
It measures 117.5 × 97.8 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Left use?
53 parts, built around the SRV05-4, XC6206P332MR and 1N4148W. 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 Left KiCad files?
From the Ch3ru09/keyboardA repository on GitHub, at the commit this page was made from: the board is left/left.kicad_pcb and its schematic left/left.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Left design in my own project?
Its repository states no licence, so its author keeps all rights: ask Ch3ru09 before reusing the design.
