Questions
How big is the Pcb esp PCB?
It measures 100 × 30 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Pcb esp use?
26 parts, built around the ESP-12F, SHT21 and LT1963EQ. 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 Pcb esp KiCad files?
From the josefadamcik/RoomMonitorPcb repository on GitHub, at the commit this page was made from: the board is pcb_esp/kicad.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Pcb esp 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).
