Questions
How big is the Esp home sensor PCB?
It measures 90 × 25 mm and has 4 copper layers, 1.56 mm thick.
What parts does the Esp home sensor use?
98 parts, built around the BME680, VEML3235, BQ25170DSG and ESP32-C6-MINI-1. 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 Esp home sensor KiCad files?
From the kamilix2003/esp-home-sensor repository on GitHub, at the commit this page was made from: the board is hardware/esp_home_sensor/esp_home_sensor.kicad_pcb and its schematic hardware/battery_charger/battery_charger.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Esp home sensor 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).
