Questions
How big is the Hass Room Sensor PCB?
It measures 55 × 40 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Hass Room Sensor use?
31 parts, built around the BME690, SCD40-D-R2, CL21B106KOQNNNE and SR0805FR-471RL. 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 Hass Room Sensor KiCad files?
From the Hass-Room-Sensor/Hass-Room-Sensor repository on GitHub, at the commit this page was made from: the board is ecad/HassRoomSensor.kicad_pcb and its schematic ecad/HassRoomSensor.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Hass Room 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).
