Questions
How big is the ESP32-S2-Dev PCB?
It measures 47 × 67.3 mm and has 4 copper layers, 1.6 mm thick.
What parts does the ESP32-S2-Dev use?
118 parts, built around the CP2102N-A01-GQFN28R, ESP32-S2, BD00C0AWFPS-ME2 and B120-E3. 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-S2-Dev KiCad files?
From the bubbab315/ESP32-S2-Dev repository on GitHub, at the commit this page was made from: the board is ESP32-S2_Dev/ESP32-S2_Dev.kicad_pcb and its schematic ESP32-S2_Dev/ESP32-S2_Dev.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the ESP32-S2-Dev design in my own project?
Its repository states no licence, so its author keeps all rights: ask bubbab315 before reusing the design.
