Questions
How big is the Env sensor PCB?
It measures 43 × 63 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Env sensor use?
29 parts, built around the ESP32-DEVKITC-VE, MH-Z19B, BME280 and TXB0104PW. 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 Env sensor KiCad files?
From the motty-mio2/env_sensor_pcb repository on GitHub, at the commit this page was made from: the board is env_sensor.kicad_pcb and its schematic env_sensor.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Env sensor design in my own project?
Its repository states no licence, so its author keeps all rights: ask motty-mio2 before reusing the design.
