Questions
How big is the ESP Module PCB?
It measures 18.5 × 37.4 mm and has 4 copper layers, 4.69 mm thick.
What parts does the ESP Module use?
15 parts, built around the ESP32-S3-MINI-1-N8 and AMS1117-3.3. 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 Module KiCad files?
From the bschan9228/MInG repository on GitHub, at the commit this page was made from: the board is Hardware/Prototype/ESP_Module/ESP_Module/ESP_Module.kicad_pcb and its schematic Hardware/Final/ESP_SoC/ESP_SoC/ESP_SoC.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the ESP Module design in my own project?
Its repository states no licence, so its author keeps all rights: ask bschan9228 before reusing the design.
