Questions
How big is the PCB ESP PCB?
It measures 96 × 61.6 mm and has 2 copper layers, 1.6 mm thick.
What parts does the PCB ESP use?
8 parts, built around the DHT11. 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 Az154za/HOME_ASSISTANT_LIGHT_SWITCH repository on GitHub, at the commit this page was made from: the board is PCB/PCB_ESP.kicad_pcb and its schematic PCB/PCB_ESP.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the PCB ESP design in my own project?
Its repository states no licence, so its author keeps all rights: ask Az154za before reusing the design.
