Questions
How big is the ESP32-Pi PCB?
It measures 65 × 56 mm and has 2 copper layers, 1.6 mm thick.
What parts does the ESP32-Pi use?
65 parts, built around the CP2102N-A01-GQFN24, ESP32-WROOM-32, M2.5 and MBT3904DW1. 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-Pi KiCad files?
From the singleboardsolutions/Obsidian-ESP32 repository on GitHub, at the commit this page was made from: the board is ESP32-Pi.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the ESP32-Pi design in my own project?
Its repository states no licence, so its author keeps all rights: ask singleboardsolutions before reusing the design.
