Questions

What parts does the Keypad use?

21 parts, built around the TL3301AF160QG. 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 KiCad files?

From the peginium/Digital_Design-Bonus_Project repository on GitHub, at the commit this page was made from: the board is kicad_design/keypad.kicad_pcb and its schematic kicad_design/keypad.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the Keypad design in my own project?

Its repository states no licence, so its author keeps all rights: ask peginium before reusing the design.
