Questions
How big is the SDWire PCB?
It measures 21.6 × 48.4 mm and has 4 copper layers, 0.8 mm thick.
What parts does the SDWire use?
83 parts, built around the FT200XD-R, USB2640-HZH-02, AT24CS02-SSHM-B and MC74HC1G04DTT1G-TP. 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 SDWire KiCad files?
From the 3mdeb/sd-mux repository on GitHub, at the commit this page was made from: the board is doc/hardware/SDWire/SDWire.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the SDWire design in my own project?
Its repository publishes it under the Apache-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
