Questions
How big is the Controller PCB?
It measures 90 × 55 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Controller use?
27 parts, built around the MAX232N. 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 Controller KiCad files?
From the telecnatron/workbench_psu_controller repository on GitHub, at the commit this page was made from: the board is circuit/controller.kicad_pcb and its schematic circuit/controller.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Controller design in my own project?
Its repository states no licence, so its author keeps all rights: ask telecnatron before reusing the design.
