Questions
How big is the Sensor PCB?
It measures 49 × 49 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Sensor use?
79 parts, built around the STM32L051K8T6, HTU21D, TPS61222DCK and TPS79718DCK. 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 Sensor KiCad files?
From the pluyckx/SensorPcb repository on GitHub, at the commit this page was made from: the board is Sensor.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Sensor design in my own project?
Its repository states no licence, so its author keeps all rights: ask pluyckx before reusing the design.
