Questions
How big is the Motherboard PCB?
It measures 127 × 46 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Motherboard use?
116 parts, built around the ESP8266EX, PMS7003M, GD25Q32CSIGR and BME280. 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 Motherboard KiCad files?
From the KhazAkar/espws repository on GitHub, at the commit this page was made from: the board is hw/motherboard/motherboard.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Motherboard 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).
