Questions
How big is the Pico6502 PCB?
It measures 110 × 67 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Pico6502 use?
29 parts, built around the SN74LVC245APW. 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 Pico6502 KiCad files?
From the jscrane/Pico6502 repository on GitHub, at the commit this page was made from: the board is kicad/pico6502.kicad_pcb and its schematic kicad/pico6502.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Pico6502 design in my own project?
Its repository states no licence, so its author keeps all rights: ask jscrane before reusing the design.
