Questions
What parts does the SecureDevBoard use?
48 parts, built around the SN75176AD, W25Q128JVSIQ, 54602-908LF and AOTA-B201610S3R3-101-T. 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 SecureDevBoard KiCad files?
From the JonasHeilig/SecureDevBord repository on GitHub, at the commit this page was made from: the board is SecureDevBoard.kicad_pcb and its schematic MainOS_RP2350B.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the SecureDevBoard design in my own project?
Its repository states no licence, so its author keeps all rights: ask JonasHeilig before reusing the design.
