Questions
How big is the Patch shield digital PCB?
It measures 197 × 71 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Patch shield digital use?
121 parts, built around the 74HC595, CAT24C128LI- and MH2029-221Y. 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 Patch shield digital KiCad files?
From the OpenElectronicsLab/OpenHardwareExG repository on GitHub, at the commit this page was made from: the board is kicad-files/rev1/patch-shield-digital.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Patch shield digital design in my own project?
Its repository states no licence, so its author keeps all rights: ask OpenElectronicsLab before reusing the design.
