Questions
How big is the Choc keyboard PCB?
It measures 116.6 × 101.1 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Choc keyboard use?
50 parts, built around the 24LC256-I/P. 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 Choc keyboard KiCad files?
From the Tybuu/choc repository on GitHub, at the commit this page was made from: the board is pcb/left/choc_keyboard.kicad_pcb and its schematic pcb/left/choc_keyboard.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Choc keyboard design in my own project?
Its repository states no licence, so its author keeps all rights: ask Tybuu before reusing the design.
