Questions
How big is the Central PCB?
It measures 175 × 90 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Central use?
57 parts, built around the MC34152D, TDA8541T and IRF540N. 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 Central KiCad files?
From the robotronik/cdfr2018 repository on GitHub, at the commit this page was made from: the board is Electronique/Central_ancien/central.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Central design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
