Questions
How big is the Furnace controller PCB?
It measures 88 × 100 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Furnace controller use?
155 parts, built around the B0505S-1WR2, MAX31855EASA+T, ADUM1301ARW and AMS1117-3.3. 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 Furnace controller KiCad files?
From the brrastak/furnace repository on GitHub, at the commit this page was made from: the board is furnace_controller_HW/furnace_controller.kicad_pcb and its schematic furnace_230V_HW/+3V3_isolated.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Furnace controller design in my own project?
Its repository states no licence, so its author keeps all rights: ask brrastak before reusing the design.
