Questions
How big is the Bob PCB?
It measures 100 × 100 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Bob use?
144 parts, built around the ADM4857AR, USBLC6-4SC6, TBD62783APG and ULN2803ADWR-HXY. 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 Bob KiCad files?
From the rene-dev/stmbl repository on GitHub, at the commit this page was made from: the board is hw/kicad/de0bob/Bob.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Bob 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).
