Questions
How big is the Cpu blitter inputs PCB?
It measures 177.8 × 152.4 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Cpu blitter inputs use?
145 parts, built around the 74HC163D, 74HC238D, CD40103BD and TX24-40R-12ST-H1E. 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 Cpu blitter inputs KiCad files?
From the clydeshaffer/gametank repository on GitHub, at the commit this page was made from: the board is Hardware/KiCad/LogicBoard/cpu-blitter-inputs.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Cpu blitter inputs design in my own project?
Its repository states no licence, so its author keeps all rights: ask clydeshaffer before reusing the design.
