Questions
How big is the Mini climate control PCB?
It measures 101.9 × 66.3 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Mini climate control use?
92 parts, built around the ESP32-S3-WROOM-1-N8, TPS62161DSG, BTN8982TA and AP2112K-3.3. 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 Mini climate control KiCad files?
From the MAIK97MAX/mini-climate-control repository on GitHub, at the commit this page was made from: the board is hardware/mainboard/mainboard.kicad_pcb and its schematic hardware/mainboard/mainboard.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Mini climate control design in my own project?
Its repository states no licence, so its author keeps all rights: ask MAIK97MAX before reusing the design.
