Questions
How big is the EspDuino PCB?
It measures 67.7 × 79.8 mm and has 2 copper layers, 1.6 mm thick.
What parts does the EspDuino use?
49 parts, built around the ATMEGA328P-AU, 74HCT125PW, ESP8266EX and LD1117S12TR-HXY. 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 EspDuino KiCad files?
From the foufee/EspDuino repository on GitHub, at the commit this page was made from: the board is espduino.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the EspDuino design in my own project?
Its repository states no licence, so its author keeps all rights: ask foufee before reusing the design.
