Overview
Interface DAC is an open-source printed circuit board by nonameCCC, from the nonameCCC/PHASE-1 repository on GitHub, published under the GPL-3.0 licence. It is a 4-layer board of 68 × 45 mm with 146 parts on 145 nets, routed with 281 tracks and 23 vias.
It is built around the MIMXRT1011DAE5A, TPS62A02ADRL and TPS65131RGE, with the W25Q32JVUUIQ, PCM1794ADB and SN74LVC2G14DBV among its other parts. Its parts include 77 capacitors, 32 resistors, 13 ICs, 5 inductors and 4 diodes. It belongs with the audio and music and interfaces and adapters boards and the NXP (LPC, Kinetis, i.MX RT) boards of this library.

Questions
How big is the Interface DAC PCB?
It measures 68 × 45 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Interface DAC use?
146 parts, built around the MIMXRT1011DAE5A, TPS62A02ADRL, TPS65131RGE and W25Q32JVUUIQ. 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 Interface DAC KiCad files?
From the nonameCCC/PHASE-1 repository on GitHub, at the commit this page was made from: the board is Interface_DAC/Interface_DAC.kicad_pcb and its schematic Amplifier/Amplifier.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Interface DAC design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
