Questions
How big is the BMP581breakout PCB?
It measures 11.7 × 13.2 mm and has 2 copper layers, 1.6 mm thick.
What parts does the BMP581breakout use?
9 parts, built around the BMP581. 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 BMP581breakout KiCad files?
From the ivarhak/compact-BMP581-Breakout repository on GitHub, at the commit this page was made from: the board is BMP581breakout.kicad_pcb and its schematic BMP581breakout.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the BMP581breakout 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).
