Questions
How big is the ReactionGameBoard PCB?
It measures 58 × 48 mm and has 2 copper layers, 1.6 mm thick.
What parts does the ReactionGameBoard use?
26 parts, built around the ATTINY24A-SSU and 74HC595. 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 ReactionGameBoard KiCad files?
From the halina20011/ReactionGame repository on GitHub, at the commit this page was made from: the board is ReactionGameBoard/reactionGameBoard.kicad_pcb and its schematic ReactionGameBoard/reactionGameBoard.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the ReactionGameBoard design in my own project?
Its repository states no licence, so its author keeps all rights: ask halina20011 before reusing the design.
