Questions
How big is the ZX BUS Mouse PCB?
It measures 99.1 × 40 mm and has 2 copper layers, 1.6 mm thick.
What parts does the ZX BUS Mouse use?
31 parts, built around the ATMEGA8A-AU, EPM3032ALC44-7N, 74LVC1G125DBV 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 ZX BUS Mouse KiCad files?
From the proboterror/ZX_BUS_Mouse repository on GitHub, at the commit this page was made from: the board is KiCad/ZX_BUS_Mouse.kicad_pcb and its schematic KiCad/ZX_BUS_Mouse.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the ZX BUS Mouse design in my own project?
Its repository states no licence, so its author keeps all rights: ask proboterror before reusing the design.
