Questions
How big is the One Base Board PCB?
It measures 180 × 135 mm and has 2 copper layers, 1.6 mm thick.
What parts does the One Base Board use?
159 parts, built around the 74LVC125AD, CP2102, L293D and LM1117-3.3. 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 One Base Board KiCad files?
From the ExploreEmbedded/OneMicro-Base-Board repository on GitHub, at the commit this page was made from: the board is Harware Design/One Base Board.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the One Base Board design in my own project?
Its repository states no licence, so its author keeps all rights: ask ExploreEmbedded before reusing the design.
