Questions
How big is the Opusdiscovery PCB?
It measures 99.1 × 99.1 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Opusdiscovery use?
59 parts, built around the 74LS384N, 74LS00SC, 74LS139PC and L7805. 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 Opusdiscovery KiCad files?
From the alvaroalea/opusdiscovery-clone repository on GitHub, at the commit this page was made from: the board is opusdiscovery.kicad_pcb and its schematic opusdiscovery.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Opusdiscovery design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
