Questions
How big is the Esp32-d2dw PCB?
It measures 22.8 × 18.4 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Esp32-d2dw use?
32 parts, built around the PESD5V0R1BSFYL. 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 Esp32-d2dw KiCad files?
From the lbernstone/esp32-d2wd repository on GitHub, at the commit this page was made from: the board is esp32-d2dw.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Esp32-d2dw design in my own project?
Its repository states no licence, so its author keeps all rights: ask lbernstone before reusing the design.
