Questions
How big is the Preheat controller PCB?
It measures 96.6 × 59.7 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Preheat controller use?
53 parts, built around the ESP32-WROOM-32D, MAX31850KATB+T, AP2112K-3.3 and 1N4148W. 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 Preheat controller KiCad files?
From the perja12/preheating_station_controller repository on GitHub, at the commit this page was made from: the board is kicad/preheat_controller/preheat_controller.kicad_pcb and its schematic kicad/preheat_controller/preheat_controller.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Preheat controller design in my own project?
Its repository publishes it under the Apache-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
