Questions
How big is the Prototype PCB?
It measures 101.5 × 83 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Prototype use?
40 parts, built around the SN74LVC4245APW and AMS1117-3.3. 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 Prototype KiCad files?
From the alttpo/cart-prototype repository on GitHub, at the commit this page was made from: the board is prototype.kicad_pcb and its schematic prototype.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Prototype 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).
