Questions
How big is the Quack PCB?
It measures 56.6 × 57.7 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Quack use?
52 parts, built around the ESP32-PICO-V3, AMS1117-3.3, SN74LVC2T45YZP and SN74LVC4245APWRE4. 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 Quack KiCad files?
From the demik/quack repository on GitHub, at the commit this page was made from: the board is EDA/quack.kicad_pcb and its schematic EDA/Panels/Back/quack_BP.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Quack design in my own project?
Its repository publishes it under the Apache-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).
