Questions
What parts does the ESP use?
72 parts, built around the ESP32-WROOM-32E, DS3231MZ/V+, SP3485EN-Y and TP4056-42-ESOP8. 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 ESP KiCad files?
From the MurilloHorvath/KiCad repository on GitHub, at the commit this page was made from: the board is Empresa-EcoQuali/MOD-ESP32 teste/ESP.kicad_pcb and its schematic Empresa-EcoQuali/EC01/outputs/EC01_KiCad_REV0_2/KiCad/01_Alimentacao_Bateria.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the ESP 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).
