Questions
How big is the Thermometer PCB?
It measures 50.2 × 34.9 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Thermometer use?
32 parts, built around the MAX31855KASA+T, MCP3002-I/P, TPS561201DDC and PESD3V3L4UG. 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 Thermometer KiCad files?
From the sullin/thermometer-hw repository on GitHub, at the commit this page was made from: the board is v1.0/thermometer.kicad_pcb and its schematic v2.0/thermometer-hw2.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Thermometer design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
