Questions
How big is the KP08Hub keypad PCB?
It measures 82.6 × 66 mm and has 2 copper layers, 1.6 mm thick.
What parts does the KP08Hub keypad use?
94 parts, built around the RP2040, CY7C65642-28LTXC, W25Q128JVSIQ and RT9013-33GB. 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 KP08Hub keypad KiCad files?
From the siderakb/keypad repository on GitHub, at the commit this page was made from: the board is KP08Hub_keypad/KP08Hub_keypad.kicad_pcb and its schematic KP06_keypad/KP06_keypad.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the KP08Hub keypad design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
