Questions
How big is the Esp433 PCB?
It measures 47.1 × 72.6 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Esp433 use?
52 parts, built around the ESP-12E, IRM-02-5 and FT231XS-R. 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 Esp433 KiCad files?
From the kekiefer/esp433 repository on GitHub, at the commit this page was made from: the board is esp433.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Esp433 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).
