Questions
How big is the Megadrive adapter PCB?
It measures 96.6 × 25.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Megadrive adapter use?
3 parts. 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 Megadrive adapter KiCad files?
From the mrfitzy/cartreader repository on GitHub, at the commit this page was made from: the board is hardware/megadrive_adapter/megadrive_adapter.kicad_pcb and its schematic hardware/cic_adapter/D411_F411_adapter.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Megadrive adapter design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
