Questions
What parts does the Thermo2 use?
7 parts, built around the 2N2222A. 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 Thermo2 KiCad files?
From the wasarob/esphome-atom-lite repository on GitHub, at the commit this page was made from: the board is themo_with_fan/thermo2/thermo2.kicad_pcb and its schematic themo_with_fan/thermo2/thermo2.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Thermo2 design in my own project?
Its repository states no licence, so its author keeps all rights: ask wasarob before reusing the design.
