Questions
How big is the BLERoomSensore PCB?
It measures 40.6 × 22.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the BLERoomSensore use?
32 parts, built around the BME280, PCF8523T, RC0402FR-07100KL and RC0402JR-0710KL. 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 BLERoomSensore KiCad files?
From the mbush91/RoomSensor repository on GitHub, at the commit this page was made from: the board is BLERoomSensore.kicad_pcb and its schematic BLERoomSensore.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the BLERoomSensore design in my own project?
Its repository states no licence, so its author keeps all rights: ask mbush91 before reusing the design.
