Questions
How big is the Ossc pro PCB?
It measures 212.5 × 99.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Ossc pro use?
499 parts, built around the 5CEFA5F23I7N, SN74LVC2G17DBV, TPS82085SILT and FCR684208R. 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 Ossc pro KiCad files?
From the marqs85/ossc_pro_hw repository on GitHub, at the commit this page was made from: the board is ossc_pro.kicad_pcb and its schematic adapters/av_adapter/dexx_video_adapter.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Ossc pro design in my own project?
Its repository publishes it under the CERN-OHL-P-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
