Questions
How big is the Altimeter PCB?
It measures 45 × 24 mm and has 4 copper layers, 1.2 mm thick.
What parts does the Altimeter use?
100 parts, built around the MS5611-01BA03, SI7232DN, BMI088 and LDL212DR. 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 Altimeter KiCad files?
From the rckTom/alturia-pcb repository on GitHub, at the commit this page was made from: the board is altimeter.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Altimeter design in my own project?
Its repository states no licence, so its author keeps all rights: ask rckTom before reusing the design.
