Questions
How big is the ESP32 WROOM 32D PCB?
It measures 65 × 45 mm and has 2 copper layers, 1.6 mm thick.
What parts does the ESP32 WROOM 32D use?
34 parts, built around the CH340C, ESP32-WROOM-32D, AMS1117-3.3 and S8050. 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 WROOM 32D KiCad files?
From the shukranwambua-maker/Code_and_ShortCircuits repository on GitHub, at the commit this page was made from: the board is ESP32_WROOM_32D.kicad_pcb and its schematic ESP32_WROOM_32D.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the ESP32 WROOM 32D 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).
