Questions
How big is the Nudge PCB?
It measures 50 × 86 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Nudge use?
32 parts, built around the ESP32-WROOM-32E-N8, AP2112K-3.3TRG1, 1N5819WS and DMG2302UKQ-7. 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 Nudge KiCad files?
From the CooperLi1/nudgev2_pcb repository on GitHub, at the commit this page was made from: the board is Nudge.kicad_pcb and its schematic Nudge.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Nudge design in my own project?
Its repository states no licence, so its author keeps all rights: ask CooperLi1 before reusing the design.
