README
READMEsd-mux stands for Secure Digital Multiplexer.
This is SD card switcher (multiplexer) designed to help automatic testing.
This project is sd-mux controller - binary for controlling sd-mux device.
Requirements:
- libftdi1 1.4 - development library
- popt - development library
- cmake - binary tool
Build:
- enter into project directory
- create 'build' directory
- enter into "build" directory
- run 'cmake ..'
- run 'make'
Install:
- enter into 'build' directory
- run 'sudo make install' to install binary into '/usr/local/bin' (the default one) directory
Note: If you want to install files into different directory then add argument to cmake command: cmake -DCMAKE_INSTALL_PREFIX=/usr .. Then again run: make make install

Questions
How big is the Sd mux PCB?
It measures 50 × 114 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Sd mux use?
52 parts, built around the 74AHC1G14GV, TS3A27518EPW, TS3USB30EDGSR-TP and ES1AL. 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 Sd mux KiCad files?
From the 3mdeb/sd-mux repository on GitHub, at the commit this page was made from: the board is doc/hardware/main-board/sd-mux.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Sd mux 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).
