Questions
How big is the X4r sb PCB?
It measures 36 × 36 mm and has 2 copper layers, 1.6 mm thick.
What parts does the X4r sb use?
39 parts, built around the 74LS86, SN74LVC1G58DCK, AT24CS02-MAHM-T and SN74LVC1G0832DBV. 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 X4r sb KiCad files?
From the chickadee-tech/x4r-sb repository on GitHub, at the commit this page was made from: the board is pcb/x4r-sb.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the X4r sb design in my own project?
Its repository publishes it under the CC-BY-4.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
