Questions
How big is the Pico vga sd aud PCB?
It measures 85 × 56 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Pico vga sd aud use?
71 parts, built around the NC7WZ16P6X, PCM5101APW, L77HDE15SD1CH4F and MBR120. 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 Pico vga sd aud KiCad files?
From the kuninet/KZ80-USBKBD repository on GitHub, at the commit this page was made from: the board is KiCAD/VGA/pico_vga_sd_aud.kicad_pcb and its schematic KiCAD/KZ80-USBKBD.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Pico vga sd aud design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
