Questions
How big is the Array PCB?
It measures 179.6 × 161 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Array use?
266 parts, built around the SPH0641LU4H-1 and M55-7002042R. 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 Array KiCad files?
From the krasin/open_acoustic_camera repository on GitHub, at the commit this page was made from: the board is pcb/mic_array/array.kicad_pcb and its schematic pcb/controller_mipi/CV.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Array design in my own project?
Its repository publishes it under the CERN-OHL-S-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
