Questions
How big is the Sd net PCB?
It measures 116.1 × 65 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Sd net use?
13 parts, built around the GL823K-HCY04, SD-006M and AM90. 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 Sd net KiCad files?
From the performance-tuned/sd-net-2.0 repository on GitHub, at the commit this page was made from: the board is hardware/sd-net.kicad_pcb and its schematic hardware/sd-net.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Sd net design in my own project?
Its repository publishes it under the CERN-OHL-S-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).
