Questions
How big is the Esp8266 PCB?
It measures 85 × 75 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Esp8266 use?
62 parts, built around the ESP-12E, DS18B20, SI7020-A20-GM and DMP1045U. 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 Esp8266 KiCad files?
From the Hackuarium/esp-12e repository on GitHub, at the commit this page was made from: the board is kicad/esp8266.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Esp8266 design in my own project?
Its repository states no licence, so its author keeps all rights: ask Hackuarium before reusing the design.
