Questions
How big is the Sbc sd PCB?
It measures 55.9 × 25.4 mm and has 4 copper layers, 4.69 mm thick.
What parts does the Sbc sd use?
17 parts, built around the LD39015M33R and TXU0304PW. 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 Sbc sd KiCad files?
From the dpicken/atari-hw repository on GitHub, at the commit this page was made from: the board is sbc-sd/sbc-sd.kicad_pcb and its schematic gtia-interposer/gtia-interposer.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Sbc sd 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).
