Questions
How big is the Auxio board PCB?
It measures 80 × 80 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Auxio board use?
129 parts, built around the STM32L496RGT6, TCAN3414D, FT230XS-R and CDBA240LL-HF. 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 Auxio board KiCad files?
From the MatthiasGeorgImhof/Hardware_CSAT repository on GitHub, at the commit this page was made from: the board is auxio_board/auxio_board.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Auxio board design in my own project?
Its repository states no licence, so its author keeps all rights: ask MatthiasGeorgImhof before reusing the design.
