Questions
How big is the Fridge controller PCB?
It measures 30 × 70 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Fridge controller use?
28 parts, built around the AO3400A. 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 Fridge controller KiCad files?
From the alexsomesan/temp-controller repository on GitHub, at the commit this page was made from: the board is hardware/fridge-controller.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Fridge controller design in my own project?
Its repository states no licence, so its author keeps all rights: ask alexsomesan before reusing the design.
