Questions
How big is the Ventilation control PCB?
It measures 70 × 90 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Ventilation control use?
184 parts, built around the STM32G070CBT6, MAX485ED, LM358 and TPS54331D. 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 Ventilation control KiCad files?
From the ucw-gadgets/ventilation-control repository on GitHub, at the commit this page was made from: the board is hw/ventilation_control/ventilation_control.kicad_pcb and its schematic hw/ventilation_control/ventilation_control.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Ventilation control design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
