Questions
What parts does the UltraLink Extension use?
49 parts, built around the SN75176AD, SN74LVC1G14DBV, ESD3.3V88D and SM712. 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 UltraLink Extension KiCad files?
From the X-Green/UltraLink-Extension-PCB repository on GitHub, at the commit this page was made from: the board is UltraLink_Extension.kicad_pcb and its schematic UltraLink_Extension.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the UltraLink Extension design in my own project?
Its repository states no licence, so its author keeps all rights: ask X-Green before reusing the design.
