Questions
How big is the Rp2040 i2s tester PCB?
It measures 51.3 × 16.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Rp2040 i2s tester use?
43 parts, built around the RP2040 and W25Q32JVZPIQ. 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 Rp2040 i2s tester KiCad files?
From the emeb/i2s_codecs repository on GitHub, at the commit this page was made from: the board is rp2040_i2s_tester/rp2040_i2s_tester.kicad_pcb and its schematic codec_pmods/nau8822_pmod/nau8822_pmod.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Rp2040 i2s tester 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).
