Questions
How big is the Diagnostics PCB?
It measures 31.5 × 17.8 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Diagnostics use?
14 parts, built around the CH340N and TYPE-C-31-M-13. 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 Diagnostics KiCad files?
From the ray33ee/radiator_rust repository on GitHub, at the commit this page was made from: the board is schematics/diagnostics/diagnostics.kicad_pcb and its schematic schematics/dev_board/dev_board.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Diagnostics design in my own project?
Its repository states no licence, so its author keeps all rights: ask ray33ee before reusing the design.
