Questions
How big is the JTAGMux 1.0 PCB?
It measures 57.9 × 41.3 mm and has 4 copper layers, 1.6 mm thick.
What parts does the JTAGMux 1.0 use?
15 parts, built around the SN74CBTLV16292DL. 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 JTAGMux 1.0 KiCad files?
From the eurecom-s3/JTAGMux repository on GitHub, at the commit this page was made from: the board is JTAGMux_1.0.kicad_pcb and its schematic JTAGMux_1.0.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the JTAGMux 1.0 design in my own project?
Its repository states no licence, so its author keeps all rights: ask eurecom-s3 before reusing the design.
