Questions
How big is the Circuit esp32-base PCB?
It measures 100 × 70 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Circuit esp32-base use?
41 parts, built around the ESP32-DEVKITC-32E and ULN2801A. 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 Circuit esp32-base KiCad files?
From the ms0503/circuit-esp32-base repository on GitHub, at the commit this page was made from: the board is circuit-esp32-base.kicad_pcb and its schematic circuit-esp32-base.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Circuit esp32-base 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).
