Questions
What parts does the Ula use?
13 parts, built around the 74LS175PC, 74LS32SC and 74LS86. 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 Ula KiCad files?
From the rcapaverde/cubo repository on GitHub, at the commit this page was made from: the board is pcb/ula/ula.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Ula design in my own project?
Its repository states no licence, so its author keeps all rights: ask rcapaverde before reusing the design.
