Questions
How big is the Simulation Main Board PCB?
It measures 243.2 × 134 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Simulation Main Board use?
564 parts, built around the ESP32-S3-WROOM-1-N4, 74HC125D,653-JSM, R-78K5.0-2.0 and R-78K3.3-2.0. 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 Simulation Main Board KiCad files?
From the Swimnato/Simulation-Main-Board repository on GitHub, at the commit this page was made from: the board is Main Board.kicad_pcb and its schematic Analog Muxes.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Simulation Main Board design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
