Questions
How big is the HiFiDAC PCB?
It measures 40 × 40 mm and has 4 copper layers, 1.61 mm thick.
What parts does the HiFiDAC use?
105 parts, built around the OPA1612AID, ES9039Q2M, TPS7A87RTJ and MPZ1608B471ATA00. 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 HiFiDAC KiCad files?
From the BlockWorker/ModularAudio repository on GitHub, at the commit this page was made from: the board is HiFiDAC/HiFiDAC.kicad_pcb and its schematic 12VLDO/12VLDO.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the HiFiDAC design in my own project?
Its repository states no licence, so its author keeps all rights: ask BlockWorker before reusing the design.
