Questions
How big is the Ultrasonic O2 sensor PCB?
It measures 44.4 × 39 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Ultrasonic O2 sensor use?
31 parts, built around the MAX3232ID and LM358. 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 Ultrasonic O2 sensor KiCad files?
From the hacklabkyiv/test-sensor repository on GitHub, at the commit this page was made from: the board is ultrasonic_O2_sensor.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Ultrasonic O2 sensor design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
