Questions
How big is the Game control adapter PCB?
It measures 99.1 × 79.4 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Game control adapter use?
32 parts, built around the NE556 and 74LS32SC. 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 Game control adapter KiCad files?
From the roybaer/game_control_adapter repository on GitHub, at the commit this page was made from: the board is game_control_adapter/game_control_adapter.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Game control adapter design in my own project?
Its repository states no licence, so its author keeps all rights: ask roybaer before reusing the design.
