Questions
How big is the I4040-sbc PCB?
It measures 100 × 100 mm and has 2 copper layers, 1.6 mm thick.
What parts does the I4040-sbc use?
61 parts, built around the RI-0515S and CD40109BE. 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 I4040-sbc KiCad files?
From the markablov/i4040-sbc repository on GitHub, at the commit this page was made from: the board is schematic/i4040-sbc.kicad_pcb and its schematic schematic/i4040-sbc.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the I4040-sbc design in my own project?
Its repository publishes it under the Unlicense licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
