Questions
What parts does the Esp32+relays use?
144 parts, built around the ESP32-S3-WROOM-1-N8, HLK-10M05, BL0942 and 74HC4052. 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+relays KiCad files?
From the akram202/PCB_PROJECT_ repository on GitHub, at the commit this page was made from: the board is In-Wall AI Energy & Control/esp32+relays.kicad_pcb and its schematic DataStream-MP/esp32_24bit.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Esp32+relays 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).
