Questions
How big is the Sub Board PCB?
It measures 50.5 × 113 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Sub Board use?
200 parts, built around the STM32F401VET6, TPS629210DRLR-ET and TPD2E001DZDR. 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 Sub Board KiCad files?
From the DennisSchulmeister/ModularMusicController repository on GitHub, at the commit this page was made from: the board is PCB/Sub-Board/KiCAD/Sub-Board.kicad_pcb and its schematic Experiments/LCD-Board/doc/schematic/LCD-Board.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Sub Board 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).
