Questions
How big is the Sensor hub PCB?
It measures 96 × 81 mm and has 4 copper layers, 1.61 mm thick.
What parts does the Sensor hub use?
126 parts, built around the LPS22HH, PCAL6408ABSHP, SCD40-D-R2 and SI7021-A20-GM. 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 hub KiCad files?
From the Aifryz/sensor-hub repository on GitHub, at the commit this page was made from: the board is hardware/sensor-hub/sensor-hub.kicad_pcb and its schematic hardware/sensor-hub/mcu.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Sensor hub 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).
