Questions
What parts does the TopLevel use?
3 parts, built around the STM32G474RET6 and BQ7697202PFBR. 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 TopLevel KiCad files?
From the K0iNguyen/LongBoard repository on GitHub, at the commit this page was made from: the board is Schematics/TopLevel/TopLevel.kicad_pcb and its schematic Schematics/TopLevel/BalcinProtecMonito.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the TopLevel design in my own project?
Its repository states no licence, so its author keeps all rights: ask K0iNguyen before reusing the design.
