Questions
How big is the Keep breathing ctrl PCB?
It measures 153 × 148 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Keep breathing ctrl use?
260 parts, built around the ICE40UP5K-SG48ITR50, STM32F427VIT6, XCL206B123AR-G and HTS221. 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 Keep breathing ctrl KiCad files?
From the CV19CO/open_controller_for_ventilator repository on GitHub, at the commit this page was made from: the board is pcb/keep_breathing_ctrl.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Keep breathing ctrl design in my own project?
Its repository states no licence, so its author keeps all rights: ask CV19CO before reusing the design.
