Questions
How big is the Multiplex driver PCB?
It measures 133 × 53.9 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Multiplex driver use?
47 parts, built around the INA282AID, ULN2803A, CD4021BE and LM317T. 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 Multiplex driver KiCad files?
From the CCHS-Melbourne/vend-matrix repository on GitHub, at the commit this page was made from: the board is circuit/multiplex_driver.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Multiplex driver design in my own project?
Its repository states no licence, so its author keeps all rights: ask CCHS-Melbourne before reusing the design.
