Questions
How big is the Shield PCB?
It measures 68.6 × 53.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Shield use?
58 parts, built around the CD4051BE and GL5516. 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 Shield KiCad files?
From the majkrzak/optikos repository on GitHub, at the commit this page was made from: the board is shield/shield.kicad_pcb and its schematic shield/shield.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Shield design in my own project?
Its repository states no licence, so its author keeps all rights: ask majkrzak before reusing the design.
