Questions
How big is the 6502 DebugBoard PCB?
It measures 205.7 × 236.9 mm and has 2 copper layers, 1.6 mm thick.
What parts does the 6502 DebugBoard use?
90 parts, built around the ATMEGA328P-PU, MAX232N, 74HC00D and 74HC166D. 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 6502 DebugBoard KiCad files?
From the DomAtTheShack/6502-Breadboard-ROM repository on GitHub, at the commit this page was made from: the board is Schmatics/6502-Debug-Board/6502 DebugBoard.kicad_pcb and its schematic Schmatics/5v PSU/5v PSU.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the 6502 DebugBoard design in my own project?
Its repository states no licence, so its author keeps all rights: ask DomAtTheShack before reusing the design.
