Questions
How big is the Cryoskills sensor kit PCB?
It measures 130 × 60 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Cryoskills sensor kit use?
95 parts, built around the FT231XQ-R and DS18B20. 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 Cryoskills sensor kit KiCad files?
From the cryoskills/sensor-kit repository on GitHub, at the commit this page was made from: the board is cad/kicad/sensor_kit/cryoskills_sensor_kit.kicad_pcb and its schematic cad/kicad/sensor_kit/cryoskills_sensor_kit.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Cryoskills sensor kit design in my own project?
Its repository publishes it under the CERN-OHL-P-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
