Questions
How big is the Cqa02303v4 cad PCB?
It measures 285.8 × 95.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Cqa02303v4 cad use?
260 parts, built around the SK6812MINI-E, BAV70 and BAV99. 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 Cqa02303v4 cad KiCad files?
From the cqa02303/cqa02303v4 repository on GitHub, at the commit this page was made from: the board is cqa02303v4_cad/cqa02303v4_cad.kicad_pcb and its schematic cqa02303v4_cad/cpu_board/cpu_board.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Cqa02303v4 cad design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
