Questions
How big is the WiFiMaster PCB?
It measures 67.4 × 54.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the WiFiMaster use?
49 parts, built around the ESP32-WROOM-32U, SN74LVC8T245PW, NCP1117ST and 1N4148WS. 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 WiFiMaster KiCad files?
From the Phunkafizer/AllSerial repository on GitHub, at the commit this page was made from: the board is Mainboards/WiFi ESP32/Board/WiFiMaster.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the WiFiMaster 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).
