Questions
How big is the ClockGen PCB?
It measures 27.7 × 17.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the ClockGen use?
9 parts, built around the SN74LVC1G14DBVR. 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 ClockGen KiCad files?
From the SSCsimsi/8Bit_Computer repository on GitHub, at the commit this page was made from: the board is 8Bit Computer ver2.0/Kicad/ClockGen/ClockGen.kicad_pcb and its schematic 8Bit Computer ver2.0/Kicad/ClockGen/ClockGen.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the ClockGen design in my own project?
Its repository states no licence, so its author keeps all rights: ask SSCsimsi before reusing the design.
