Questions
How big is the 8EA PCB?
It measures 76.2 × 49.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the 8EA use?
30 parts, built around the ADC0809CCN, 74LS04PC, 74LS30PC and 74LS32SC. 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 8EA KiCad files?
From the Fred72z/ORIC repository on GitHub, at the commit this page was made from: the board is BUS_ORIC/Extensions/Entrees_analogiques/Kicad5/8EA.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the 8EA design in my own project?
Its repository publishes it under the GPL-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
