Overview
STEREOPI is an open-source printed circuit board by pavithvishnu, from the pavithvishnu/STEREOPI repository on GitHub, published under the Apache-2.0 licence. It is a 6-layer board of 90 × 40 mm with 187 parts on 203 nets, routed with 2,093 tracks and 590 vias.
It is built around the LM26420XSQ, SP3003-02JTG and LAN9513-JZX, with the MF-MSMF200-2, PDTC143ET and SSB44 among its other parts. Its parts include 89 capacitors, 51 resistors, 7 inductors, 4 diodes and 1 switch.

Questions
How big is the STEREOPI PCB?
It measures 90 × 40 mm and has 6 copper layers, 1.6 mm thick.
What parts does the STEREOPI use?
187 parts, built around the LM26420XSQ, SP3003-02JTG, LAN9513-JZX and MF-MSMF200-2. 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 STEREOPI KiCad files?
From the pavithvishnu/STEREOPI repository on GitHub, at the commit this page was made from: the board is StereoPi.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the STEREOPI design in my own project?
Its repository publishes it under the Apache-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).
