Questions
What parts does the Termometr use?
100 parts, built around the MCP6031-E/MS, LM1117-3.3, LT1009CD and PT100. 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 Termometr KiCad files?
From the bambuchaAdm/termometr repository on GitHub, at the commit this page was made from: the board is pcb/termometr.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Termometr design in my own project?
Its repository states no licence, so its author keeps all rights: ask bambuchaAdm before reusing the design.
