Questions
How big is the Io box PCB?
It measures 200 × 120 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Io box use?
76 parts, built around the R-78E12-1.0/X9, R-78E5.0-1.0 and SN74AC14N. 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 Io box KiCad files?
From the vekkuli/mv_io_box repository on GitHub, at the commit this page was made from: the board is kicad_project/io_box.kicad_pcb and its schematic kicad_project/io_box.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Io box design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
