Questions
How big is the ESP32 Breakout PCB?
It measures 83.5 × 89 mm and has 2 copper layers, 1.6 mm thick.
What parts does the ESP32 Breakout use?
74 parts, built around the LM358 and BSS138. 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 Breakout KiCad files?
From the GadgetReboot/ESP32_Breakout repository on GitHub, at the commit this page was made from: the board is KiCad/ESP32Breakout.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the ESP32 Breakout design in my own project?
Its repository states no licence, so its author keeps all rights: ask GadgetReboot before reusing the design.
