Questions
How big is the Thermostat PCB?
It measures 176.3 × 70.4 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Thermostat use?
34 parts, built around the BME680 and BC547. 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 Thermostat KiCad files?
From the SouprP/thermostat repository on GitHub, at the commit this page was made from: the board is hardware/thermostat.kicad_pcb and its schematic hardware/thermostat.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Thermostat design in my own project?
Its repository states no licence, so its author keeps all rights: ask SouprP before reusing the design.
