Questions
How big is the ADAU1761-breakout PCB?
It measures 50 × 20 mm and has 4 copper layers, 1.6 mm thick.
What parts does the ADAU1761-breakout use?
23 parts, built around the ADAU1761BCPZ, 0402WGF4701, CL05A106MQ5NUN and CL05B104KO5NNN. 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 ADAU1761-breakout KiCad files?
From the romkey/i2c-dsp repository on GitHub, at the commit this page was made from: the board is hw/ADAU1761-breakout/0.0.1/ADAU1761-breakout.kicad_pcb and its schematic hw/ADAU1761-breakout/0.0.1/ADAU1761-breakout.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the ADAU1761-breakout 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).
