Questions
How big is the Xlink CR PCB?
It measures 50 × 40 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Xlink CR use?
22 parts, built around the CH552T and CD4148WTP. 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 Xlink CR KiCad files?
From the ttahsin-bey/XLink_CostReduced repository on GitHub, at the commit this page was made from: the board is Hardware/C64/Xlink_CR.kicad_pcb and its schematic Hardware/C64/Xlink_CR.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Xlink CR design in my own project?
Its repository states no licence, so its author keeps all rights: ask ttahsin-bey before reusing the design.
