Questions
How big is the Diva card PCB?
It measures 85.4 × 53.7 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Diva card use?
96 parts, built around the RP2040, AP2112K-3.3, ATECC608A-MAHDA-S and WS2812C. 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 Diva card KiCad files?
From the diva-eng/diva-card repository on GitHub, at the commit this page was made from: the board is diva-card.kicad_pcb and its schematic connectors.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Diva card 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).
