Questions
How big is the Keypad PCB PCB?
It measures 45 × 45 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Keypad PCB use?
20 parts, built around the ATMEGA32U4-AU. 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 Keypad PCB KiCad files?
From the Mygi27/KEYPAD-PCB-V1 repository on GitHub, at the commit this page was made from: the board is Keypad PCB.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Keypad PCB 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).
