Questions
How big is the Audio PCB?
It measures 127 × 73 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Audio use?
164 parts, built around the TJA1043T, TJA1100HNZ, TLE8366E V50 and 10MQ040N. 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 Audio KiCad files?
From the cubitel/car-audio repository on GitHub, at the commit this page was made from: the board is pcb/audio.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Audio 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).
