Questions
How big is the Incubator bottom PCB?
It measures 99.9 × 73.7 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Incubator bottom use?
57 parts, built around the ATMEGA328P-AU, DS18B20, DS18B20Z and MBR0520L-TP. 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 Incubator bottom KiCad files?
From the Hackuarium/simple-incubator repository on GitHub, at the commit this page was made from: the board is kicad/incubator_bottom/incubator_bottom.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Incubator bottom design in my own project?
Its repository states no licence, so its author keeps all rights: ask Hackuarium before reusing the design.
