Questions
How big is the Timing PCB?
It measures 63.5 × 41.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Timing use?
12 parts, built around the 74LS161DC and 74HCT574D. 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 Timing KiCad files?
From the rustbox/cuddly-robot repository on GitHub, at the commit this page was made from: the board is eeprom-sync/vga/vga/timing/timing/timing.kicad_pcb and its schematic eeprom-sync/eeprom-sync.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Timing design in my own project?
Its repository states no licence, so its author keeps all rights: ask rustbox before reusing the design.
