Questions
How big is the SodaIDE v2 konami case PCB?
It measures 100 × 65.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the SodaIDE v2 konami case use?
30 parts, built around the 74HC245D, 74HCT138D, 74HCT32D and 74HCT74D. 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 SodaIDE v2 konami case KiCad files?
From the Danjovic/Soda-IDE repository on GitHub, at the commit this page was made from: the board is hardware/V2/SodaIDE_v2_konami_case/SodaIDE_v2_konami_case.kicad_pcb and its schematic hardware/V1/Soda_IDE.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the SodaIDE v2 konami case design in my own project?
Its repository publishes it under the CC0-1.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
